I'm back again, psychology this time

So, I just can't give up on this. I decided to see a psychologist, at the suggestion of my psychiatrist.  I spent the whole first meeting with him crying. He asked me questions about how long I have been pulling, and about my family life, and about what stressors I have in my life. It was a hard conversation.  It brought up a whole lot of feelings, mostly feelings of shame and disappointment.  That's a lot of my life: shame and disappointment. I don't want to feel this way.  I'm very disappointed in myself for not being able to stop this behavior even after 27 years. I'm ashamed because...I don't know why.  I'm just ashamed.  I'm ashamed that I pull my hair out.  I'm ashamed that I cannot get close to people.  I'm ashamed that I have allowed people to take advantage of me and walk all over me and take away one of the most important things in my life. It's all tied up in my self worth. I have no self worth. Sometimes I feel like I just want out of this body, and into a new body.  I've messed this one up pretty bad with the hair pulling. It's not much fun being me. I'll continue to follow up with how my psychology appointments go and hopefully I will be able to document some progress.  This is really my last hope.  I have tried everything else.
