How do you open up to someone you hate?

Ehh... I'll make this short. I wrote all the names of all the students of my current grade. I marked out all the es and kept the "nice" people, even though they didn't do anything to me, I looked at it. I marked out all names except 6. I realized all the ones im my cl were marked out and only 1 not from the other homerooms. I'm planning on asking the counselor about this, even though I hate her. I'm just trying to confirm if my homeroom cl is the cl where all the left-overs are put. It's weird that the whole cl (everyone) has to go to the other periods with the same scedule and we have the same electives. I don't really like the people whom aren't marked out, so I'm planning on making friends with the one whom are marked out, but I don't know how if I hate them. I feel as if I'm the only one who likes what I like, the one whom is not made to make friends, but to be alone. I see the world in different view than others and my best friend is an... ant... that died already..
