I NEED ADVICE PLEASE HELP ME?

Well you see, I'm starting 7th grade in a few months, & I get so depressed thinking about school because I don't have any friends. Just thinking about it makes my eyes water. & I can't make new friends because in 5th grade people made up rumors that I was a lesbian, & it kept spreading. So because people think that I'm a les they're too grossed out to be my friend. (I'm straight by the way) Please give me the best advice possible. Thanks. [:
