I can't stop Peeling my Lip...?

Okay, I have had this habit for over 4 yrs now and it is super annoying, When I get bored, stressed, or just really anything I will start peeling my lip. I have tried lip balms, every kind, and nothing makes me stop wanting to pick my lip. It is like a really nice sunburn where it peels. I know sounds really gross but I really want to stop. Please HELP any suggestions. I have a daughter now and it has been really nasty to take care of her and i have to wash my hands because i was messing with my lip.
