am i overreacting?

to start of, i'm a teenager in high school. because i am literally the only gay person at my school, it's kind of depressing. go ahead and call me a pussy, but it fucking sucks to see everyone guy with their girlfriends and you're alone. i'm not going to home coming because no one will even go with me. sometimes, i get so down that i have no one to hold hands and spill my mind out to; i can't do anything but think about this guy that i like. i have even tried to sign up for gay dating apps, but that won't help because they are all grown and it would make it any better. online dating only goes so far and still, no one will talk to me. i'm at a loss for what i should do.
