Caving In (?)

Okay so lots of cause for celebration... well somewhat.
So yesterday I had this auditon for a mariachi group. (Yes, I'm still a Mexican musician. Sue me. :P) And I've kind of been freaking out about it because this is an actual professional group that performs and gets paid to do so) and so I've been trying to get back into vocal shape, along with my other things to juggle (school, my new job which has yet to start, commitments, not worrying my mom, etc.)
Well, I made it into the group! As a matter of fact, I impressed the owner of the group and he might want me to be in 2 groups. But at any cost, I am suuuper psyched and so I grabbed a few friends to go eat at McDonald's last night after I got back. We made our way to McD's and while the nuggets were steaming hot, we started taking about my audition and the group I would be in and that lasted for a good five minutes. While we made our way through the box of nuggets, it occured to someone to bring up the many flaws society has with me. It always starts with one comment about my makeup and from there everyone goes on a rampage. I swear, it turned into like a half hour session of how there are so many things wrong with me. And so this conversation, the one out of many I've heard time and time again is about how I'm this great person and they wouldn't change a thing (yet they insist if I change everything, I'd be amazing) The went on and on about how they wanted to give me a makeover and change my look and everything they thought was wrong with me.
But outnumbered 3 to 1, I couldn't say much to defend myself. They were right and I was wrong. So while they all plotted my makeover, I was fuming silently. There's nothing wrong with me. I'm perfectly fine and even though they think they're helping me, it hurts. Am I just being paranoid?
