You might want to expand your focus - if you can't promise to commit to a long-term project due to your health concerns, try talking to local temp services. It won't be tech work, but it will be work and a paycheck. With low expectations of continued work. Low pay, too, but it sounds like you only want some money, not an amount so large to kick you out of your programs.

I've also gotten tech gigs from temp gigs - "Hey, I know I'm just a temp, but I also do tech work and noticed some things I could automate for you, if you'd like some help."
