Thank you for sharing! I'm not good in emotion stuff or comforting people, but I would like to try and tell you that I think that it takes courage to share those things! I don't have a lot of friends either, but that's ok. I learned that sometimes people you only know in the Internet are caring more than anyone around you!
I'm sorry for the people who choose to abandon you, they are stupid, they choose not to see your real you. Like a diamond, when you find it it might look like a ugly stone, only with the proper care and treatment they become pretty and you can see their real value! So I would say they missed out on something beautiful!
