What do you do if you hate how people see you?

Well how do you know that is what people see you as? Its what you see yourself as, doesnt mean that everyone else does. As for your question are you really happy when you are being true to yourself, and are you really happy when you lie. Neither one will bring you happiness, so there is no point in pursuing those. You need to change your view on self image, and stop looking at yourself in a such shallow way, you are more than a body.
