Your mom sounds a bit like my mom.

I think that therapy could help you.

I've sort of given up on myself though----My issue is in every relationship. I fully expect anyone at any moment to turn on me and get angry or leave. My doc says that its a part of my hypervigilance that's a part of my PTSD. My body/mind are on 24/7 high alert. I wish it could change, but after so many years of healing, its one of a few symptoms that doesn't ever get any better. You sound better than I do though, so I think there is hope for you. Hugs.
