Anxious Mom To Be

Hi all. I'm expecting o. The 25th of November and I am in a group of about 13 ladies and we are all expecting. So the one who was 1 week ahead just had a miscarriage. I'm putting on this strong face but everytime I close my eyes I picture myself and I don't see myself surviving it after TTC for over a year. I can't get this out of my mind. I'm slightly stressing ow I need help
