hey!
i don't really know what i'm doing writing here either - i saw this page through a server error, but some of the stories here just break my heart - so i tried to answer...
people can't deserve to be this alone.
you are brave to write this - and strong, since you didn't opt for an easy way out, and honest.
(and i don't think you should be ashamed of how you feel...)
try not to hate your parents - maybe they had no choice, or they could have died - it says nothing of whether they wanted you or not.
life is weird and even cruel sometimes...
i'm an art student, so for me my drawing has always been an outlet and a salvation. and it always gave me source of self-worth, of strength - so if you can - try and be really really good at something - no matter what it is.
try photography, or writing. try to ride horses! (i never tried yet...) or even snorkeling, or skuba diving - there must be more to life than just lonelieness and despair.
(and please please please don't say you are too old for this - my wonderful step-mom learned to windsurf a couple of years ago - and she's about 67 now).
there must be something that will give you happieness!
what do you like?
