High school Rumors (WRONG CATEGORY I KNOW)

Backstory:

in the seventh grade i thought i was transgender and that thought had stuck with me until eighth grade year. the popular kids were understanding and whenever i was around and they made a gay joke or smth of the sort they would apologize and etc etc. i know they talked about me but it obviously wasn't anything like "yeah lets get this tranny dyke and ruin her life" or anything like that .

Now it's August 2018. I'm about to be a freshman in high school. i'm playing volleyball at a local sports club until october because i didn't make the team at my high school. everything's going good, i still had my bestfriend, and we were basically doing everything together every day.

The school is great, the teachers are amazing, and everything's going good. it's about let's say november / december whenever people start talking about my past in middle school. at first it was the whole "she had braces and we called her rachet bracket" (inside joke) and "she played violin pretty good" and stuff like that.

then it got into a lot of people talking about me being trans. that's whenever it got bad. in october i started dating my current boyfriend and i obviously told him everything about middle school. he didn't care about what other people said and was like "i still love you no matter what so your past doesn't affect now"

people brought up old instagram posts and everything and started showing people. and there's still people talking and idk what to do. i know i labeled it rumors and that's because people are trying to say me and my lesbian friend are dating or that im still trans and yeah.

i do think at this point it's starting to die down but i'd still like advice incase it starts up again. i don't want this to affect my relationship in any way either.
