Help I’m weak with anxiety

I don’t know if having a previous mc made the anxiety worse but I am having a very weak night tonight. It’s very bad. My mind is full of anxiety about losing my child. I’m 35 weeks. I’m almost there. But I know there’s bad things that can happen. How do I get my mind off these bad bad thoughts? I asked another mom group and their way of trying to help was to tell me “it happens it happened to my friend” like that DOES NOT help at all. It makes it a million times worse and of course I KNOW IT HAPPENS hence why my mind is consumed by terrible thoughts. I need some help if anyone has been through it too and found something to work??
