Highschool.

Well, I'm a freshman and I don't know how to communicate. I get a's and b's in all my classes. I always manage to have some form of friends that I usually end up only putting by myself to not look like a loner. Ive been around such charming people that i feel so drawn to intellectually, spiritually, emotionally, intuitively. but I ruin it by not balancing out the relationship by giving off an equal amount of good vibes though verbal and non-verbal communication. Also I dont know enough about myself at all. Advice?
