I don't remember feeling like it at primary school, but from secondary school onwards I've always felt on the outside of any friendship groups I am in. I was in a group of friends at school, I always felt that they were all warmer to each other than they were to me, and preferred the others to me. We are all still in contact with each other now, and although I'm still friends with them all I always feel like they don't value me and that I'm just "there".
It's the same in all other friendship groups I've had in my adult life. People like me (I think) and I have lots of friends but it's all always on a superficial level,and I think people think I'm just "there". I don't think anyone would give me priority as a friend or refer to me as one of their best friends, although I think most friends would say they like me. It's happened on online groups too.
I know it's probably my state of mind but I don't know how to change it really. Am I perhaps better off being on the outside of everything and staying in with everyone? Or I'm thinking perhaps groups of friends just aren't for me and I need to be friends with people on an individual basis?
