@perennialloner,
Thankyou so much, your answer just seems to get it!
I did eel really self conscious about it at times because the amount of times I'm in a group where there are some people I've never met and one of them will just go up to a bar and order everyone drinks except me or show a picture to them all and just miss me out or pass a joke on and just miss me out, even on a bus full of strangers I'm always the last person to be sat next to, which isn't a bad thing I suppose but I've seen people stand rather than sit next to me; I'm not fat I don't have bad hygiene so I really don't get what's wrong with me
It's every group of people I'm with weather it's childhood friends, uni people, people at work
So yes I do agree that I can get paranoid over it which stops me feeling comfortable which probably makes it even worse but sometimes I feel people only like me when I've had a lot to drink but then I worry about them thinking that I'm incapable of looking after myself when I get really drunk
I went out and constantly got told not to stay out if I didn't want to and we'd just got there so I instantly felt uncomfortable/in the way and felt like if I stayed is ruin their night or if I left I would by looking like I'm just sulking off by myself
