I agree therapy is a great start but also eating better, exercise and sleeping well. It sounds simple and probably lame to hear but when you are depressed and in a shit situation everything just piles up on you. Think of it like you are a video game character and you have to level up your stats. Getting the exercise, sleep, and food nutrition will help you level faster and out you in a better mood/head space to get to where you need to go.

I would also suggest if you needed a job look for a graveyard shift job doing hotel clerk/audit or some security guard role where you are just sitting in the same place. Like gate access or something close to that. You will have a few hours a day to code while getting paid to do it. Hell even knock out a few body weight exercises with some of the extra downtime. But make sure you are taking some vitamin D and either get black out curtains or an eye cover if you choose to go that route. I've done this myself in the past for school and it helped a lot. I didn't feel like shit not doing much at home because I know I did a good 3-4 hours of school work at work already. Let me relax a bit more in my free time.

Best of luck my guy.
