Anybody using the Android SDK as a Fullstack alternative?

Note: In this rant I will ask for advices, and confess some sins. I will tell my personal story- it will be long.

So basically it has been almost 2 years since I first entered the world of software development. It has been the biggest and most important quest of my life so far, but yet I feel like I missed a lot of my objectives, and lots of stuff did not go the way I wanted them to be, and it makes feel frustrated and it lowered my self esteem greatly. I feel confused and a bit depressed, and don't know what to do.

I'll start: I'm 23 years old. 2 years ago I was still a soldier(where I live there is a forced conscription law) in a sysadmin/security role. I grew tired of the ops world and got drawn more and more into programming. A tremendous passion became to burn in me, as I began to write small programs in Python and shell scripts. I wanted to level up more seriously so I started reading programming books and got myself into a 10 month Java course.

In the meanwhile I got released from army duty and got a job as a security sysadmin at a large local telco company. Job was boring and unchallenging but it payed well. I had worked there for 1 year and at the same time learned more and more stuff from 2 best friends who have been freelance developers for years. I have learned how to build full-stack mobile apps and some webdev, mainly Android and Node.js. However because I was very inexperienced and lacked discipline, all of my side projects failed horribly, and all attempts to work with my experienced friends have failed too- I feel they lost a lot of trust for me(they don't say it, but I feel it, maybe I'm wrong).

I began to realise I had to leave this job and seek a developer job in order to get better, and my wish came true 6 months ago when I finally got accepted into a startup as a fullstack webdev, for a bit lower wage but I felt it was worth it. I was overjoyed.

But now my old problems did not end, they just changed. My new job is a thousand times harder and more intensive than the old one. I feel like it sucks all the energy and motivation that was still left in me, and I have learned almost nothing in my free time, returning home exhausted. My bosses are not impressed from my work despite me being pretty junior level, and I feel like I'm in a vicious cycle that keeps me from advancing my abilities. My developer friends I mentioned earlier have jobs like I do and still manage to develop very impressive side projects and even make a nice sum of money from them, while I can't even concetrate on stupid toy projects and learning.

I don't know why It is like this. I feel pathetic and ashamed of my developer sins and lack of discipline. During that time I also gained some weight that I'm trying t lose now... I know not all of it is my fault but it makes me feel like crap.

Sorry for the long story. I just feel I need to spill it out and hope to get some advices from you guys who may or may not have similar experiences. Thanks in advance for reading this.
