Does anybody get the feeling nobody cares about you?

I'm a 16 year old boy who goes to high school. I have friends but i always feel like they don't care about me. This is why i try to hang with different friends, but i also get the feeling my different friends are like "Hey what is he doing here in our group?" I'm also shy and not really talkative cause i always get a sense of if i say something to someone, I feel like i'm gunna say sumthing stupid or something lame. Basically my life right now is like a cycle everyday. I wake up, go to school, study, go to academy and study, and go home, eat, and sleep. I live my life in solitude and my life has no excitement. I want to have new friends who likes to hang out with me and share comments. Everyday i dream of going to college, so that i don't hear criticisms about me in highschool. I feel like i'm running away from my own problems. I just need someone that talk to about this but i can't because i feel embarred. Please, don't answer this question with "Just be yourself" because i have tried that a million times and i'm giving up on it. I want to feel independent, loved, and like a somebody.
