I don't have many friends of my own, but my girlfriend has a very large group of friends that I've hung out with several times before and I got along quite well with the majority of them. Last time we all went out together, I got too drunk and I had to leave the party early with my girlfriend. 

Because of what happened that last time, I've felt like all her friends hated me. This all happened months ago but I haven't seen them since. I was invited to a party tonight but I was too anxious that no one would want me there and I could ruin the party with my bad vibes, so I decided not to go. Now some of her friends are messaging me saying they were sad I couldn't make it, and after telling my girlfriend the truth about why I bailed she seems pretty upset. It's too late to go now though.

It's not the end of the world I suppose, there will be more events in the near future and I'll push myself to go to those, but because of my anxiety I'm now going to be by myself on a Saturday night sitting at home while everyone else is out having fun.
