Always hated my teeth!!!

Well let me start off by telling you that ever since I can remember I've always hated how my teeth look. I never smile if I do I smile with my lips closed or I cover my mouth. People usually tell me that my teeth are not bad and I don't really need braces but I hate to smile and thats never good, and usually people that tell me this have perfect teeth and don't know what's like to be self concious about your smile.
