Why me?

I have a serious crush on one of my friends brothers and I love hanging out with him and we text each other alot and were really good friends and I wish I could tell him but I don't know how his sister would feel about that and he's in the 7th grade. And I'm in the 8th grade.

And then this boy in the 8th grade I'm head over heals with but he's ugly and he's not interested in me that way

Everyone thinks me and him are a couple because me and him sit alone together at lunch but ugh I don't know he always sits with me and I always smile when he's around and I've tried everything to get over him. Nothing's working. And my friends are complete butts because they always joke around about it and ask him if he likes me and laughs at me when he says no. They always give clues to him that I like him and they act like it's a joke and that it's funny. But I where to tell there crushes that they liked them all of a sudden I'm the bad friend.

So basically I'm in love with two different guy friends I have and I have no idea on what to do. And the worse part of all of this I ALREADY HAVE A BOYFRIEND! Why me?
