I hate my life i need help im depressed.?

I hate my life! I'm six months pregnant and my baby (boy) isn't looking to good. He has serious heart problems. The doctors tell me he may not make it. That he may die inside me, due to heart faliure. That is the most treatning problem. He also has a brain ventricle that is enlarged (not good). He is a Down Syndrom Baby. His heart leaks, the tricuspid valve is not working properly and causing blood to flow backwards back into the top chamber (right atrium) and is making it enlarged and the other chambers are not the right size either. I'm so afraid that he will die. That I won't get to hold him... That I will have to have a funeral for him. (Do they do funerals for people who are not born?) I can hardly stand all the stress. I have a one year old daughter that I take care of everyday I am a stay at home Mom. She is the only thing that makes me the slightest bit happy. Yesterday was my Birthday, now im 20. I wasn't even happy then. I constantly try to find things to distract myself. and Im running out. If he dies I don't know what I will do. I am going to loose my mind.... Any sugestions?
