it is fun when ppl younger more than 10 years just entered into coding and tech scene offers solutions to solve my problems

which is nothing wrong and i encourage that

but then they miss core concept of how stuff should work and are not able to see real fundamentally broken problems

and then assumes im stupid
and then i want to burn them to ashes

I just realized that all I did the last three weeks was about SCSS and Twig. I didn't write a single PHP line (or please, I just added some variables inside an existing array) for 3 damn weeks.

Man, I feel empty inside

Hey guys, first time writing here.
Around 8 months ago I joined a local company, developing enterprise web apps. First time for me working in a "real" programming job: I've been making a living from little freelance projects, personal apps and private programming lessons for the past 10 years, while on the side I chased the indie game dev dream, with little success. Then, one day, realized I needed to confront myself with the reality of 'standard' business, where the majority of people work, or risk growing too old to find a stable job.
I was kinda excited at first, looking forward to learning from experienced professionals in a long-standing company that has been around for decades. In the past years I coded almost 100% solo, so I really wanted to learn some solid team practices, refine my automated testing skills, and so on. Also, good pay, flexible hours and team is cool.

Then... I actually went there.

At first, I thought it was me. I thought I couldn't understand the code because I was used reading only mine.
I thought that it was me, not knowing well enough the quirks of web development to understand how things worked.
I though I was too lazy - it was shocking to see how hard those guys worked: I saw one guy once who was basically coding with one hand, answering a mail with another, all while doing some technical assistance on the phone.

Then I started to realize.

All projects are a disorganized mess, not only the legacy ones - actually the "green" products are quite worse.
Dependency injection hell: it seems like half of the code has been written by a DI fanatic and the other half by an assembly nostalgic who doesn't really like this new hippy thing called "functions".
Architecture is so messed up there are methods several THOUSANDS of lines long, and for the love of god most people on the team don't really even know WHAT those methods are for, but they're so intertwined with the rest of the codebase no one ever dares to touch them.
No automated test whatsoever, and because of the aforementioned DI hell, it's freaking hard to configure a testing environment (I've been trying for two days during my days off, with almost no success).
Of course documentation is completely absent, specifications are spread around hundreds of mails and opaquely named files thrown around personal shared folders, remote archives, etc.

So I rolled my sleeves up and started crunching as the rest of the team. I tried to follow the boy-scout rule, when the time and scope allowed. But god, it's hard. I'm tired as fuck, I miss working on my projects, or at least something that's not a complete madness. And it's unbearable to manually validate everything (hundreds of edge cases) by hand.

And the rest of the team acts like it's all normal. They look so at ease in this mess. It's like seeing someone quietly sitting inside a house on fire doing their stuff like nothing special is going on.

Please tell me it's not this way everywhere. I want out of this. I also feel like I'm "spoiled", and I should just do like the others and accept the depressing reality of working with all of this. But inside me I don't want to. I developed a taste for clean, easy maintainable code and I don't want to give it up.
