I have a facebook page. I noticed that there was another fb page with my name & picture that i did not create.?

So i clicked on it. It sure enough was my picture had my exact name, and just for the record i'm very sick w/ chrohn's disease, weigh almost 85 lbs. So under info, it said i'm a skinny *****, under "likes" says all i do is cause drama, along with vulgar info, mind u, and anyone w/ facebook knows at the side of your homepage gives u a list of people u may know, so all my friends and family is seeing my pic and thinking hmm maybe Sarah has another page, and clicks on it only to read that crap. Isnt that stealing my identity, slander,cyber bullying, harment? I tried 2 get ahold of facebook, i reported it, saying this is a fake profile, impersonating me, and they still didnt take it down. I know darn well who it is, i just dont know what else i can do and if this is illegal
