Rapunzel,
I too am Divorced and find it very hard to be alone.Right out of H.S.(20 years ago) I moved in with my then boyfriend. After that I was with my brother and sister-in-law and then I met my now best friend lived with her for a few months then I met my current x lived with him and got married and divorced. Now back living with my best friend/roommate. I like the way that you described being an "emotional vampire" I am very much like that with my poor roommate. She has no life of her own because I am afraid to do anything alone. We shop together and workout at the gym together, Eat together. The thought of doing any of this alone scares me. I am in the process of finding a T and a PDoc so I haven't yet addresses this issue. I just wanted you to know that I know how you feel.
