HELP ME PLEASE

So I'm 14 and everyone knows I like boys and stuff but I have never done anything with one at all.  I was ALMOST raped when I was 13 so I am kinda scared of guys but I'm getting a lot better. There has been a lot of word said I out me being a slut and a skank and a prostitute.  Some boy heard this after he started talking to me and told me to kill myself.  I am merging schools next year and there is already a rumor saying I'm pregnant and how I have STDS and how I'm a whore and I just don't know what to do. I get a lot of unwanted attention from guys and I can't help it.  I don't want most of it and I'm honestly really scared. Can someone please give me some advice.
