Welcome to my world
There is no easy way to solve this, Sunshine. I have been living with it for a long time, as have you. It does take its toll on the family.
The best I can do for you is to listen, and to say that I understand, especially when you say you are "at the end of your tether".
The things that have helped me in the same situation are:
- getting medication for myself, to alleviate the stress
- yoga/exercise, for the same reason
- finding the RIGHT professionals to help my husband, including finding a psychologist who specializes in severe depression
- getting release letters allowing his mental health team to discuss his situation with me and for me to be allowed to make and follow up with appointments for him
- a whole lot of compassion and support... I virtually lived here at PC and at a few other support sites for spouses of those with severe depression. I don't know what I would have done without my kind friends here
- I also tried attending a NAMI meeting but it was extremely upsetting and I never went back. No fault of theirs, but it wasn't for me, at least not at the time.
I'm really, really sorry for your family that you have to go through this. You're not alone, though -- there are others who understand.
