How do i even say this. TRIGGER WARNING

Today we have been told our baby will have no chance at life once she's born if she makes it to term. Her condition is getting worse and I cant let her be born and be in pain everyday of her VERY short life (if she even made it to birth) Right now I cant even find any words. I am sat sobbing trying not to let my boys know how upset I am atm. We are going to end our preg. We never wanted this, we are in so much pain with this 'choice' but both choices will cause us a lot of pain. The many thing we want is our baby not to be in pain :(
