How to stop obsessing..

TTC and 5 miscarriages.. now having a hard time conceiving.. how do you stop obsessing over it and let it happen when it happens. It’s literally consuming my life and I don’t even do the things I love anymore. I never want to go out or do anything because I can’t focus on anything else but TTC. Its so hard and heartbreaking and honestly it’s ruining my relationship with my SO. I am trying so hard to stop obsessing but I feel like I can’t. How did you stop??
