Hey Wears, Mort here- Wishing you strength as always. Looking at things in here, and on the subject of finding something worthwhile to do... Maybe this is just a "me" thing, considering I made it my job and stuff, but have you considered looking into programming/coding and/or web design? Even having no former education, nowadays there's loads of tutorials out there teaching people the basics and more. You could get into the programming if you think you'd be up to it at your own pace, and later look at how to put those skills to use. (Admittedly, I'm not sure how much help I could be there- I just work a regular office job for all intents and purposes, although I know "freelancing" is definitely a thing- Which would allow you to have that flexible schedule you need.)

If coding itself is a bit too mentally intensive, web design is probably harder to get into, but potentially rewarding. Don't know terribly much about it I must admit as it's not my field of study, but to sum it up briefly, it's to make websites "look nice"- Which is something also often required.

Just an idea I'm throwing out there- Hope it's food for thought, at the very least.
