TL; DR: please save me from IT hell

Note 1: this is a rant that comes after a couple other rants I'm going to call "family business saga" from now on because I feel like this is gonna go on for a while

Note 2: the following may look exaggerated but it's because of how pissed off I am at said person

So I have to help this one family member with his computer but he's worned me out so much last summer that I can't stand him (it's all tech based). At all. Both in person and via text calls. I dread and become pissy each time he's nearby, just his presence makes me want to jump in a hole and stay there for eternity.
And he's not the smartest cookie in the jar when it comes to tech, so he comes to me for help (instead of going to my brother. Aaagh why doesn't he go for my brother as well, it's mentally tiring having to "help" him - as he doesn't learn what I'm trying to teach him even after several attempts). I don't really mind being sought for help when it comes to tech, but this guy takes it one step further.
He entered my room with his computer in his hands saying this friend of his has installed W7 on his PC (why didn't he handle all the things he wants to do, it would save me a lot of anger containment) and that I *had* (it's always "YOU HAVE" because I'm a tech-ish person and I'm in uni for CS) to help him do a bunch of things.
So he boots up the thing and there are 32 updates to do, so I'm guessing that he didn't boot it up after the OS update until now. He leaves my room and I sigh out of relief. He comes back with the AC remote complaining it's too hot in my room and that he's gonna put it down a degree or 2. Jesus christ do not tamper with my AC settings, it's fine to me. The updates are still going on. He leaves again.
The computer takes its time to update and so does he. I'm happily playing minecraft when he comes back, the computer off after updating. He looks at it and says "why is it off?". I reply back "it finished updating.", trying to keep my cool. Even the most simple questions are irritation inducing.
He reboots it and lets it run. After it boots and it's ready to go he just stays there for like 2' without doing anything because the hard drive light was going off. I think he thinks the computer is going to explode if he touches it while the light is blinking 😬
He goes to connect the computer to the internet and gets all surprised that the computer doesn't recognize our home's internet (he has been here before with his computer, I guess, so he had connected, so I think he was expecting it to auto connect like that). I tell him that the computer doesn't recognize our home's connection because it has had a fresh OS installation and so it didn't have any connection registered. He types in the password and the connection is established.
He them starts going on about that he wants to get these pics on the business' website and how does he put them in his computer and all that. I do that for him and he's all like "how did you do that?? 😮" like it's a magic trick
And he's always going on at everything as if it's all a big undoable thing. "How do I do this? You know what, do it yourself and show me because I don't wanna fail". Dude. Bro. Everything - EVERYTHING - you are afraid of doing is undoable. EVERYTHING. Good christ.
I swear I've never felt so glad I'm going back for uni next week

All summer I've been working at a company doing some full-stack development. Starting my last year in university, I really wanted some real life experience that ties into my studies.

I did not expect to find horrible, undocumented, code that has been written 5 years ago, where the senior developer who wrote it doesn't even know what it does. The worst part? They are STILL not documenting! I tried to document, but got this in return "you don't have to document everything. Especially if it is understandable". But they don't even understand their old code!

Monday morning, we had a meeting and they asked what I thought of working here, seeing as I am done this week. I respectfully told them that their code is not readable, and it will make it hard for new employees to understand. The boss in return says "you're the third newly hired employee this summer to say this... Maybe we do have a problem then"..

No shit. Please for the love of God, comment your code!

So I'm in my last year of university. The GPA is high. Did one internship the summer after second year in one of the best companies in my country. Third year in my department we do a semester long internship for 5 months, I joined a company and worked on back-end using Go. This was the spring semester and I wanted to continue working in the summer. The internsip company didn't tell me anything so I looked for a job. Found one that paid great, I was getting the salary a new graduate was getting. I worked as a full-stack there. Mostly prototyping, the company was new and I was in the R&D side. After 2 months the company had some budgetary problems and we parted ways. I was in the market again for part-time job in my senior year and because of my prior experience with Go, a friend mentioned me to a company executive he met and I had an interview and got in as a full-stack part-time dev. This was for some background information.

My story is;

The work is actually great in terms of what I do. I'm learning a lot here. The problem is that I'm having imposter syndrome for the first time ever. The projects are demanding and because that I'm part-time they take time to finish. There are no due dates or anything but sometimes the CEO is coming to me and saying "Aren't you finished with it?" or "Are you going to finish it soon?". Because that I'm more qualified in Javascript and React when they gave me my current frontend project I told them that its better if they give javascript/frontend projects from now on so that I can do a better job finishing them. What the CEO told me after that was, "Then hopefully you'll finish them sooner.". The people are nice and stuff like this only happened 2-3 times and the lead that I'm working with acknowledges my pros and cons and we have a good relationship, when I do something wrong he tells me why and how I can improve my code. But I just can't get over the syndrome and for some time I actually thought they would fire me when they get a full time dev.

Everything is great for some time. It's my fourth month and I think I felt this way because this is the most demanding job I have with senior year and also I didn't know people that well because I was the new guy. Although I still have concerns, have you ever felt this way? If you share tips or any recommendations I would feel great.

Thank you for reading.

Let's be honest - given the state of the world today, the more I listen to Megadeth, the more I relate to what Dave Mustaine has been pissed off about for a few decades now. Oh, you don't know who Dave Mustain is? He was, like, the 5th guy in Metallica. Rather, he was the bass player until he got fucked over because he was a dick and thrown off the first album Metallica did. Don't worry - he did OK. He formed Megadeth and still had quite a successful musical career. Why am I ranting about him? Simple - A lot of his lyrics are darker than Metallica's. I honestly don't know what the fuck I'm doing with my software/personal/professional life right now. I've got ideas & dreams, but all this COVID shit is just draining the fuck out of me. Sometimes I feel like I've failed - most of the lifeforms on this planet manage to procreate. Well, that didn't happen for me. On the down side, I didn't get to be a father. On the up side, I didn't punish the life of a child with my own brands of mistakes, ignorance, and stupidity. My life is littered with male failures. My biological father (paranoid, schizophrenic ) died at 58, doing everyone around him a favor. My grandfather on my mother's side died of colon cancer at 69 (so-called reformed alcoholic, manic depressive on lithium with great abusive tendencies). My step father who adopted me? Sure - he loved me. He just never understood me. "Computers are just a tool". Fuck you, 'dad'. Go play with your horses and tell me what I'm doing isn't meaningful. Where was I? Oh yes, almost killing myself last summer. I think between COVID and my own colossal screw ups & paranoia I went over the entire fucking edge. I pulled myself out of it with the help of medication, counseling, and learning to just let shit blow up because "it's not my problem". I'm still angry. Perhaps that's the only thing that keeps me going from time to time. I'll leave you with a quote from Ghandi - No, not that idealistic, limited one, Mahatma Ghandi. From his grandson, who managed to really pick up what he was putting down - Arun Ghandi:

“Use your anger for good. Anger to people is like gas to the automobile - it fuels you to move forward and get to a better place. Without it, we would not be motivated to rise to a challenge. It is an energy that compels us to define what is just and unjust.”
