I'm saying a little prayer for you right now.
I don't know if this helps, but from the perspective of the brain-injured I can tell you that I absolutely despised all the people that I was closest to after my concussion.
Some things to think about...
None of my antagonistic attitudes indicated any "real" feelings. I was truly angry at the time, but it had nothing to do with how I actually felt about the persons in question. I was angry and frustrated at the world in general.
I was hurting and desperate. I couldn't always control my actions, and as I realized how unkind they could be, that became an added problem.
I needed people at the same time that I was pushing them away. Oddly enough, one of the things that helped was getting a puppy.
I still struggle with my feelings toward people, though it is improving. As I recover, I can more often identify feelings and actions for what they really are - and sometimes help my friends to do the same.
If you can realize that these actions aren't personal - though they certainly seem that way - maybe that can help.
