I'm not the type of person that likes to hang out with people.

I'm a bridesmaid (not willingly) for my boyfriend's brother's wedding, and she's a bit dramatic. I don't participate in her parties because I don't know any of her friends. She was upset that I didn't go to her parties, and I try to explain that I'm not a sociable person but she didn't care. She's like "That's how you make friends". I'm not social at all. It makes me panic. I just got back on my medicine. I went to her bachorette party last weekend, and I felt like an outcast. All of her friends were snobs and over 21, so they did a lot of drinking. No one spoke to me. I felt like I didn't belong there at all. She just text me asking if I was getting my nails done. I'm scared to tell her that I'm not because she can be a real b-word.
