Why can't I taste anything?

I'm really not kidding, when I was a kid, I was licking my lollipop, I was moving it up and down, and it shredded my tongue. I have huge cut marks all over my tongue now (I'm age 16), and I gradually started losing tastes in certain foods. I'd rather not have my parents pay a hospital bill, so I've been wondering if there's some problem. Also, if I eat foods with high acids (citrus mostly) for some reason my tongue starts bleeding. Not sure if that's related, but I'd like any helpful information!
