I dont feel any emotion good or bad.?

Nothing bothers me. But nothing REALLY makes me happy. Im not suicidal or depressed but im also not content or happy. Other peoples pain or suffering doesnt bother or concern me. I feel no real love for any one...not even parents. But I dont hate any one either. I truly laugh at funny things. and i make jokes. But they are just jokes. Im insensitive. My ex girlfriends problems seemed trivial and rediculous to me. Racial or religious slurs against me dont bother me in the least. I am callous and blocked to the world around me.
