My new job is dull, and i dont fit in. ive wasted two years,scared of having another depressing year ahead.

my new job is waitressing and its so dull and easy. i dont fit in with anyone else, so im hanging around all day, getting the work done, which my boss says is great but i feel isolated. i do suffer from social problems, and disorders, but i still manage to get by in life, and people usually want to be my friend. though i just have nothing to say to anyone, and tey all talk to eachother and im an outcast. ive been quiet mu whole life, then in turned into a crazy two years of being mentally ill, obsessive, binge eating, and all of this crazy stuff. i dropped college twice, didnt enjoy it, and now when i thought everything was looking up, my workmates dont seem to like me. i dont have any friends right now in my life, so i thought id make new ones but i cant interact. im quite sensible and although a laidback atmosphere in the restaurant may seem quite cool, i actually prefer a serious organised go to work, earn the money, be friendly kind of thing. but its not like that, and if i was sociable i know id enjoy it but im not! im 18, and dont like the idea of uni, plus i love to perform but i have no degrees anyway. ive wasted two years doing nothing. even if i do this job for a year, im scared im going to be depressed agin for another year, plus ive lost all my hope for the future because i have nothing to look forward to. i used to have dreams of being a singer/dancer etc, but now i want to live each day and be happy but i just cant seem to do that! also i made myself all confident for the interview and put on this act when i started and everyone seemed to like the look of me, but by the end of the night it was like everyones views of me had changed. i dont dislike anyone, but i things can irritate me easily. please help me!
