Prayers for you and your family You are so brave, I completely believe in the power of prayer and hope it helps you get through this tough time and that there are many great times ahead.
I am sending good vibes your way. Yes, this sounds scary but I know you will be fine. Yes, being on a vent for a few days will be uncomfortable but ask them to keep you sedated. After a few days they can take the tube out and then take you off sedation. I don't know if this is an option.
