Need to vent

Just need to vent and I don’t have anyone to go to. I am currently 19 weeks pregnant with my first baby. We tried for 7 long years and finally got pregnant with ivf. We recently found out that our baby has hypoplastic left heart syndrome, meaning the left side of the heart isn’t growing the way it should. Baby’s will have to get surgery a few days after it’s born and again when around 2-3 months and finally around 2-4 years old. It’s so devastating and I am so stressed out. I don’t know how to handle this. My husband is just as stressed as I am. I feel so alone. This news broke up and kind of took away my excitement about being pregnant. My husband doesn’t understand how I feel bad get mad at me for things. I understand he’s stressed too but there are days when I am trying to be okay and he just stressed me out so much. I just really feel alone and so hurt
