Work also gives you structure in your day. It also means you have to practice enough self care to take a shower, do laundry to have clean clothes to wear, have at least some human interaction. Also having money is important.

If you’re unemployed and can do drugs all day, wallow in self pity, be disconnected from other humans, no haircut in months, etc. That will make your mental health worse. Also when money runs out and no new money is coming in, getting actual help to improve your situation gets much harder. Small problems become bigger problems.

I know from experience.
