Will I get depressed?

I've been biting and picking my finger skin for as long as I can remember and its begining to get to me so bad..... I can cry and cry and cry, and the embarassment is getting so bad.. I'm afraid to show my hands because I'm scared of what people will think. I'm constantly trying to hide my hands from the world. It looks horrible and discusting and I'm sick of it. :'(
