I'm with you nearly all my friends are only neighbors. I've not kept in touch with any friend from childhood, college, or past jobs. I always felt like they didn't know me, so why make the effort. It seems mutual, they didn't try and keep in touch either.
After accepting myself, I did reach out to two of my electroligists though and it really surprised me by the reaction. They of course knew I was trans from the beginning of treatment, but with them I've been able to feel normal and authentic. We've gone to dinner a number of times. One even came to group therapy to support me.
I really think accepting ourselves has been the key to make real friends. If the first two are any indication, I will have many more Real friends in my future.
