I'm afraid of what people think. I know society always encourages us not to feel that way, and I hear countless people telling me that I can't be afraid, but it's not that easy lol. When I enter rooms and am around people, I fear that they are thinking bad things about me. I'm not being selfish thinking that everyone is thinking about me, but I dealt with this a lot when I was in school. I was bullied my entire time there, and I guess it kind of introduced me to those feelings.
I'm also afraid to make friends. I seriously want some, but I'm afraid of what happens once you have friends...like trying to keep them interested, that fear that they would just get bored of you one day, or people just not caring anymore.
And of course, rejection.
