How to ignore ual gay thoughts?

I've accepted the fact that I'm gay (im fourteen) & it's hard because I entered highschool. I see pda all the time and its so hard ignoring the fact I can never be like that. Also, theres like no open gay people in my school that I know :$ I try to ignore everything, but I always know that I'll never feel like that for the next four years until I can move out and finally be open. None of my friends will understand right now, and I think it's too early to tell them who I really am. My self esteem is really low because of various reasons and I just want to find love...
