I also walked out of teaching 7 years ago. I was in a good position earning a good salary, but my senior management started to recognise my "moods" and "erratic behaviour" lol. I walked out one day and never returned. Classic self destructive behaviour.

I now run my own business. I'm sure that is something you could do yourself. A lot of people seem to like making things and selling them online etc. Perhaps if you're an arty person, you could do this. I'm sure there are things you could do where you can work at your own pace without any pressures.

Good luck with it all.
