17 year old in club? Fight with friend.

Okay... so.... I’m on vacation and my friend is here too with her family. There is a club right by our hotel and they’re having an “all ages” night. My friend and her boyfriend are 18, I’m 17, so we went over to club. Immediately I was uncomfortable. I am not into drugs and have a bit of social anxiety so it was starting to make me anxious. We were standing in line and the people behind us were talking about how drunk they were (not to mention they said earlier they were my age- 17...) and this guy was hitting on every girl around him. one guy came up next to us and threw up. But my friend still wanted to go so. I asked the people in front of me what the price was and she said 55.00. I didn’t have that money on me, much less was I going to pay 55.00 to go see an artist I didn’t even know, be shoulder to shoulder with random sweaty people, and have my anxiety act up. My friends boyfriend has anxiety attacks a lot so I was also thinking about him in this situation, but evidently all my friend could think about was herself. I told her I wasn’t paying 55.00 to get in and that my parents would be mad - but really I just said that to get out of there. We eventually left after telling her many times her and her boyfriend could stay and that I was just not going to pay 55.00 to go in for two hours. I kept apologizing and she snapped at me and told me to “shut up or else she was going to get even more fucking mad”. After an awkward walk back to our hotel, I came into my room and just broke down crying. I don’t know how to feel about it. I feel like I ruined my friends night. I feel like a loser. I feel like I should go out of my comfort zone more. I feel like I’m not being rebellious enough. I feel offended that she got angry at me. I keep thinking that they’re talking about me and how much of a loser I am. After my parents consoled me a little bit, I went to go buy a water in the vending machine and over the railing I saw the line still backed up but now people were booing and screaming because they weren’t letting anymore people in and a fight broke out. The lady sitting there and watching told me that was the third fight that broke out. I just don’t know how to feel about it and I am sitting here feeling terrible. My parents keep saying that they’re “proud of me” but I just feel like shit. There are many wise girls here and I just wanted to know some opinions on the situation. Am I in the wrong? Is there something wrong with me because I didn’t want to go in there? Sorry this was so long. Hope you all have a great night. Thanks if you read it all and are willing to reply.
