OMG i hate my friends!!!! PLEASE HELP ME?

basically my friends are popular and sometimes on the weekends theyll pick me up, drive around with me for a few minutes, if that (were 17) and then take me home. they'll talk to me in cl but they wont hangout with me during lunch time. i know it probably sounds like theyre really mean, but theyre really good people, which is why i dont get why they're doing this to me. today i had lunch in the bathroom (i dont like to be seen unless i am with people) and i just dont know what to do. it's my senior year, and i know it seems like i should just go get new friends, but that's easier said than done. please help me. thanks
