How can I make my senior year great?

I'm 17.This will be my last year in high school.I'm a quiet laid back person.I become more talkative once you get to know me.A lot of people don't like me for no reason.I want this year to be better since its my senior year.I don't have too many friends.Last year I tried getting a makeover while I got compliments it didn't make people like me.I'm tired of being an outcast and talked about.How can I make things better this year?My school has no clubs so I cant join any kind of club.
