Feeling Awkward and Out-of-Place in Social Situations

Just yesterday I hung out with a group of five other people, two of whom I was already friends and the other three I had met that day. I think putting myself out there is overall a good thing, as getting yourself out of your comfort zone can lead you to new opportunities. That being said, yesterday was probably the worst I've felt in a long time. Now, these other five people already knew each other so I was the new person to the group. Maybe it's just a natural feeling, but I felt so indescribably awkward and out-of-place. I don't think I said more than ten words that entire night, even though I wanted to. I was so uncomfortable in my own skin, not because of the people, but because of myself. I felt so disgusted with myself that I couldn't think about anything other than negative thoughts. It really put me out of the mood and I'm pretty sure the others noticed. Then, I proceeded to feel bad about being this way in the first place, that I'm the weird one for overthinking such a simple situation. I hate this. I just hate this cycle that I can't seem to get out of.
