Should i commit suicide?

im a **** up. a big **** up. i wasted my secondary school years and left with no gcse's. im not stupid just had a very awkward adolescence. now im 17 almost 18 and heading nowhere fast. everyone i knew/know are heading off to uni in a years time and im headed nowhere. my life sucks. i dont like the people i hang out with, and i strongly believe the feelings mutual. my family sucks. i hate my life. every single bit of it. just typing this up now is motivating me to overdose on some hard drugs or something. what do you think? honestly if you were in my position would'nt you do it??
