Whats the point :/

Everyone at school hates me beacuse of my scars, because im a lesbian, because im different, cause i smoke, drink and do drugs. Im the neighbourhood weirdo and everyones afraid to talk to me. Im all alone. Ive been cutting for 5 years now and still found no escape. Ive been out for 2 years (sorta only certain people really know) and i feel that i smoke drink and do drugs as an escape. No one understands what im going through. So the whole point of this is to find a point. If i have no freinds, no girlfriend, no life, my bodys barely working whats the point of going on. no one will miss me? or even notice im gone? me being gone will just make everyone elses life better, no more weirdo right? Writing this note i still cant find a point? help?
