WOW, you're only 17, and your lobes are already 1 1/2 inch? Thats crazy. But I like it xD
Anywho, back on topic. A similar thing happened to a friend of mine, his ears were at a pretty large size, can't remember exactly what size, it was around 1 inch, and he got into a fight and his lobe got ripped pretty severly. Its been afew years since it happened and this is whats left of his ear

Sorry, if its too big, and sorry for the poor quality, it was taken on a phone xD
But yeah, I know his only option now, is surgery, or live with it, and that's probably your only option too, regardless if its healed of not. Its probably best to contact a plastic surgeon asap and talk over your options.
Goodluck with your poor lil ear, and be sure to update for us!
