If you life sucks, it's mostly likely because you made it that way! Fate/luck/misfortune is only responsible for some of your life, if you don't do anything to make the bad better then you have only yourself to blame.
I know I used to feel **** about stuff so I did something about it and it's within everyone to sort that, be it just exercising so your not fat, or helping others to make your life more fulfilling, and last but not least if your superficial making money however you can.
A saying I always think it pretty true is...
Life is not easy if it was it would be boring! (make a good point, who plays computer games on the easiest level and enjoys them)
Considering you were given the gift of intelligence, consciousness, and being human on as far as we know the only planet with thaat ability which is probably less likely than winning the lottery 1000times in a row, you should count yourself so insanely lucky that every second on this earth, the one chance you get, is precious.
I agree with Rob that wasting that is insanely pathetic.
