I can relate to this very much. Since I entered recovery I have been in school and I just feel so alone because I really don't have what my peers have: careers, spouses, etc. If I remain focused I will get there.
Literature was always my way of understanding the world. Novels helped me feel comfortable. Your post reminds me that there are others like me. Sometimes I just accept the fact that most people I encounter every day are not interesting to me. Younger people especially appear very shallow and callous to me.
One reason I drank was that I felt so alone, ugly, and damaged. Now I understand that I have to love myself. But I have to learn and I have to make mistakes. Making my sobriety a priority is one way I love myself.
Maybe start a meetup group for misanthropes and loners!
