i also want to add that i really don't know how to go about even trying to heal them. i got EC because i was obsessed with putting on blistex like ten times a day, then i ended up with an allergic reaction when i tried chapstick once (it has different ingredients), so i stopped using anything and then my lips started cracking, and i picked at the cracks and here i am. i also want to add though that before then i didn't completely leave my lips alone. i would rub them together a lot and do other things (not as harsh as picking and biting, but still)...
i've tried supplements and dieting, but nothing too intense because i'm sort of skeptical- i dont think my problem is internal, although some people think that they are all internal.
sorry if this was long, i'm just a little desperate :(
