I also try to act how I think people want me to act and I take most criticism to heart. It's because I'm too afraid to be myself and potentially get rejected. I'm not a risk taker.i'm insecure about... my confidence. im not really the most confident person and i take criticism very strongly.. if theres something different about me that people don't like, i try to change that which is bad in my opinion.. in the end, i soemtimes show people a "fake" side of me, which makes me mad at myself.. and im not depressed or anything aha.
