I haven't actually played your game yet but stumbled on this page looking for totally regular RPGs on twitch. I checked your dev log and I hope your life gets on a solid track soon.
Honestly, if you can make a game, it should be fairly easy for you to get into programming, data analysis etc., lots of courses on Udemy etc. My friend had success getting a high paying tech job by joining a coding bootcamp that doesn't require upfront payment but you sign an agreement to give them a small portion of your salary for 2 years after you land a job.
Look these up and maybe that's a way to get a less stressful day job and then focus on yourself a bit. Also please do excercise and stuff, it has been wonders to by own mental health, way way more than I expected, also really boosts self-easteem etc,
