Lonely

I realized about the only friend I have is a great lady named Kim.
I guess it is my fault. Another friend reminded me what I did last year to someone else. Ever since then nobody really talks to me or wants to do things with me. I totally forgot about that. I forgave myself and asked for forgiveness .
I understand if people don't trust me.
why can't people let it go and let me move on with my life.
I am sick of being lonely. I guess I will go back into my shell I worked so hard to get out of when I moved here.
