I don't have to be "cool."
I don't have to be silent.
I don't have to be her. 
I don't have to be loud.
I don't have to be loved by him to be okay.
I don't have to be happy all the time.
I don't have to agree to be accepted.
I don't have to hide.
I don't have to have the answer.
I don't have to be perfect.
But I do have to be me.
