I just found out my baby has a heart defect.?

I am 22 weeks pregnant. I went to an ultrasound at 17 weeks but not a medical one. Just one to see what the sex is, which we found out was a boy. I just went in for my first ultrasound at the hospital and they said his heart only has two instead of four chambers and the wall was not properly devoloped and there was only one valve thing leaving the heart, and his stomach is on the right side instead of the left side same as the heart. I plan on going next week to get tested to see what his chromosomes look like. There are several possibilities, he could have down syndrome, he most likely needs to have atleast one heart surgery, but everything depends on how he handles all of it, continues to develop and such. I'm really scared. I am more scared to lose my lil hector than anything else. Does anyone have any advice or anything reasuring they could tell me..?
