Sad and terrified

I have just come from my anttenal appointment at the hospital and I saw one of the head obstetric doctors with my husband. I have just found out my uterine segment is now at a dangerous thickness, it's only 1mm. I'm scared as I'm only 25+4 today. The Dr said the hospital is relying on when I feel like something is wrong before they act.

What if I don't know when something is wrong, what if I have a complete rupture and baby and I die. I'm fucking scared!!!! I can't stop crying because I feel helpless and lonely. If I contract again it can split open and then time is of the essence. I don't have any family who I speak with, I only have my husband and he gave me a husband response, which doesn't help me feel better.
