Never been myself

For as long as i can remember I have never been myself, I look at the mirror where i know i should be but all i see is a vacant forlorn shell. I try to fit into these boxes for others that are way too constricting but i contort who i am to fit upon their shelves. I give my whole self completely and never choose me, I am a slave to my weakness... the feeling of being needed. But not because I am me but because I am easily molded into who they want me to be. Don't be yourself be this person to please me and ill give you whatever i think that person needs. Who am I and why am I not myself?
