what do i need to do?

[speshlj14]

i've had something since i've been 12. since then i've noticed that my nipples were getting more sensitive and my dad said it would go away. well it's been 2 years now and they've gotten worse. i can't even take off my shirt without somebody making fun of me or staring... i'm pretty active and i'm not fat. so i don't really know what's going on. could somebody help me out?
