Smile and love yourself for who you are. Don't let people make you feel like you're worthless. You are you and if they don't like it then show them the door. Live your life the way you want and not how others expect you to.

I am who I am and I'm not fussed whether you like me or not. I've dealt with a lot of shit in my life, so to be honest I don't care what you've got to say. :)
