You are definitely not alone. I feel the same way at times. I just got out of a 8 month relationship cause I was sick and tired of feeling like I was the main problem and that all the bad was my fault. It hurts to feel alone and to feel not wanted. What helps me is really trying to open my eyes at work and see how many people I work with really do care about me. I do the same thing at a friends house, do they seem distant or are they really listening? I am pretty sure many more people care for us than we all seem to believe, and see.

Recovery for us is possible, I'm starting to believe it more and more every day.

Have you tried meditation? Exercise? Healthy eating?

Meditation I believe would benefit you a lot, it benefited me a lot, but once I stopped my mind went straight back to the b/s of before. You have to be consistent and committed to the things that make you feel good/happy inside.
