Have I ruined my chance of having friends this year?

I'm usually a sort of loner type person who has always struggled to make friends and sort of just ends up left out of things because people perceive me as weird/boring/quiet but I'm on my year abroad (third year of uni) and at the start of this year actually got invited to a few things. So I went on one night out I was invited to and was feeling kinda left out and awkward around the people I was with so I got drunk to try and make myself feel more at ease. Everyone else was also drunk but far less than I was and I ended up getting so drunk that I both humiliated and physically injured myself. After that, there was one girl from the group who still bothered with me and invited me to things so I thought it might not be that bad. But I found out there's another night out tonight which no one had really mentioned to me and they're all going together in groups and no one asked if I wanted to go in their group so I'm taking that to mean I'm not really invited even though I could technically go and no one would object to me being there, they'd probably just ignore me. I try not to let these things bother me but it does kinda hurt that even the one girl from the group who was still inviting me to things has organised to go in another group without me. Have I totally ****ed up my chances of having friends by being a strange drunk liability?
