I hate my friends?

I am serious, I have never had a real good experience with making friends. I am a junior in high school and I jsut hate them. My friends are really smart A/B honor students and so am I, but whenever we are doing a project or something in cl they always act like I am stupid and nevr acknowlede my intellect, but acknowledge my other friends intellect. And my bestfriend (who thinks of me as a bestfriend too) never invites me to his house for sleepovers, but instead invites other kids and leaves me out of the loop. The thing that really pissed me offf is when 2 of my friends called me a follower. my friend jack was hanging with sophmores and I was like "Why is Jack hanging with them?" to my friend Michael. Then the sophmores and Jack called me over so I went over there to speak with them. When I got back Michael was like you ask why Jack was hanging with sophmroes but you go over there your a follower.
