How to sleep when loved ones pass away?

So I've had two cousins die literally one after the other in horrific ways. One in a house fire and another in an accident. They were both shocking, and my heartaches. My great aunt passed a month before but she was old, my cousins were young. I feel restless and find it hard to sleep because I'm nervous about 2023 taking another one from us. I just hope not. I feel a certain anxiety like when my grandma died years ago, I kept thinking something bad would happen to someone else and my heart races. Any tips on getting rest? I just feel drained from all this death one after the other.
