My suggestion would be to offer teaching by internet?
For the moment, many schools around are closed, so I suppose this is a good time to get started. And you wouldn't have to concentrate for more than half an hour or so at the time.
If I where you, I would make an advertisement right away, while the situation is like it is.
If you are very unsure about how to do this, you might offer free help in the beginning, either for a month or so, or the first two or three lessons,
This way you will also see if you are able to do this kind of work or if it gets too stressful. And you might get yourself some accommodations (? I think? Ask your students to write how clever and nice you are?) -EDIT




RECOMMENDATIONS



was the word I was looking for
(I might add...I can often keep going for up to three months before I collapse.
So start slowly. Twice or three times a week is more than enough. Working might give you a boost, and you might get so exited that you feel you could work a lot, but that is most likely your adrenaline talking. Don't listen! Adrenaline is a big lier! Stick to your plan, you can expand in half a year or so, if you still feel alright)
If online lessons and help for homework works ok for you, I guess it's a fine possibility to earn a little bit?
I was in part time work for several years with me/ cfs.
As long as you're able to work a little bit, it's a VERY good thing to do.
I supporte you a hundred percent on this.
If, in the end, you're not able to work after all, you have at least tried.
