I have no advice, but I just wanted to send hugs, sorry you're going through this. I know just how draining stuff like that can be.
I think each of us do have a point at where we have to say 'sorry, that's enough'. And stop working.
For me, even though I'm still 'in' my M, I think I've learned more about myself, and I think I've 'grown up' more since I stopped working than I ever did trying to figure out how to make things work. I've also learned a lot about H by watching how he tries to fill in the hole.
