How long will my credit accounts continue to revolve after delinquent?

I havent been able to make any of my credit card payments for the last 4 months and they are still coming in with late fees. Will they ever quit adding late fees? Does this debt ever erase if i dont pay it? Im only 17 and my credit is very important to me during this part of my life, getting an apartment, student loans, another car.etc.
