My son was born with down syndrome, should I kill myself?

WOW Can you sound more scared?!?!?! You have this new child and you find out he is going to be to some degree disabled for the rest of his life. It's normal to freak BUT you need to pull it together man! This is your baby, you helped make him and he needs a dad. He is a human being! Start looking into what has to be done to help him be the best he can be and help. Quit thinking of your self here, this is not about you.
