very confused right now ..

I have a 2.5 year old and a newborn. I shouldn't have anymore kids for health reasons (I could but it would be high risk). I keep feeling like I want another baby but it just wouldn't work.. not enough bedrooms, not big enough car, not safe to go through another pregnancy. I have a hard time accepting it. I also get really jealous when friends and family announce pregnancies. Will this go away? Please tell me it does. I hate feeling this way 😓
