You're not alone at all . I feel like this all the time, please don't feel bad about it. I realize this when I sit in my local pub, drinking alone at an empty table meant for four people, in an isolated dark corner, and then I realize how uninviting I must be when other drunk people don't even want to come over and sit with me, or even abuse my good nature to get a couple of free drinks out of me. That's particularly bad for me - I'm so unwanted that people don't even want to use and abuse me.
