I honestly need help, what could possibly be happening to me, am i becoming anti social?

i guess i answered my own question because i know i am not anti social but i truly need help. all my best friends from college are home for tgiving (i've been home i did comm. college this yr) and i am not happy to be with most of them. when it is all 7 of us i seriously have thoughts of suicide i am not joking. all the 'on the surface' conversations are a bore to me. i like it in smaller groups we can talk more in depth but even so i prefer staying home. am i a narcissist b*tch? i enjoy my own company, is it possible that i am sick of them even though i barely see them? i havent made any new best friends at my new college. wow i want to throw up, what is wrong with me??? depression signs? i dont think so but i dont know what could be going on. maybe im just sick of these same old faces
