Aspergers or antisocial?

Sounds like you understand what your problems are so that counts out mental illness, so unless you get some perverse ual gratification out of abusing the people in your life, its purely your choice. Could also be that your just a selfish, juvenile, brat that needs to grow up a little and realize you get out of life and relationships what you put into them. If you want people to care about you, them you have to care about them - compasion is NOT a one way street. The bottom line is ANY human behavior, unless your retarded or mentally ill, is a CHOICE that YOU are ultimitaly RESPONSIBLE for and if you don't like the results your behavior ellicits, then YOU must take the steps to change the negtive behavior that is adversely affecting your life. The sooner you get a handle on this the better because the majority of people who behave like you have two typical outcomes: prison or death! Start by sincerly thanking your grandparents for taking you in, apologize for treating them badly, promise to improve your attitude and then do it - then see how their attitude towards you improves. But if you can't find it in yourself to be the bigger man and do this, for your and their sake, than you're hopeless and a burden to sociey that deserves to be as miserable as you make the people around you...YOUR CHOICE!
