I started dating this guy, and he's amazing. We are really similar and suspect he's got BPD but he had a head injury that has left him with some psychosis problems. 

Whenever he goes to sleep, he has like minis psychosis episodes. He can't be woken up and sometimes these happen at really bad times.. Like now, we have plans and he just passed out and it's making me so angry. I know it isn't his fault and he can't help it but what about me? Now I'm having to deal with a bunch of stress and anxiety without support from him, though I'm always able to help him in need. 

It worries me that he won't be there for me ever when I need him and that this is just going to be one-sided and difficult. My BPD is very much managed, I see a therapist regularly and have most of my symptoms under control.. But this new relationship is testing my coping mechanisms and showing me where I still need improvement. 

How do I deal with this welling rage and sadness? Coping mechanisms?
