Everything,

I'm a liar because I won't tell you everything.
I'm stupid because sometimes I'm wrong.
I'm ugly because my face isn't perfect.
I'm a pushover because I love making people happy.
I'm a loser because I'm not a friend in your group.
I'm fake because I'm too nice.
I'm weird because I'm not like you.
I'm fat because I eat.
I'm very insecured because I care about what people thinks of me.
I'm no fun because I'm not always hyper.

Don't try to tell me what I am because I already know. I'm me.
