There isn't anything wrong with you at all. I also have a weird reaction I can't fully explain. I get irrationally irritable with my girlfriend if i'm not getting something I need in the relationship, even if its something with my husband or boyfriend. It also happens if I haven't had sex in too long. It makes absolutely no sense and is never her fault, but I think I've gotten the hang of managing it.
You just keep working on getting to a comfortable place for you. People who love you will want to help.
