Problem with lips

I have posted before about this but i am posting again because i am having no luck and am starting to get depressed by this problem, here's the problem:
I am 16 years old male.A few months back i began to get slightly chapped lips and while i was washing, the skin on my lips got wet and came off with great ease. this soon got worse and since then i have had many layers of my lips come off due to brushing my teeth or washing, or even drinking. iam now left with no actual skin on my lips and it is very uncomfortable.
it even effects my speech, not very good as i have german oral exam tomorrow.
this problem isn't chapped lips it is a case of not actually having a proper layer of skin on my lips.

PLzzzzzzzzzzzzzzz help would appreciate it sooo much.
