My best wishes to you. I am sorry to hear all you have been through, although I don't paint I do write short stories and can very much relate to the desire to create, then becoming something overwhelming and too much.

Crazy is right, time for yourself is just as important, and reminding yourself there are others out there can sometimes make all the diffrence.
All the best and remember, one day at a time. Maybe give yourself one task to do tomorrow. Walk along the block. Or take a photo of something that caught your attention. Nothing major just little things for yourself each day.
Take care.
