I have an irrational fear of the idea of losing a member of my close family (father, mother, brother and sister).

I had the happiest childhood and I love them. But for as long as I can remember, I’ve had this terrible fear from the moment I wake up to the moment I go to bed. I compulsively check my phone throughout the day to see if someone called me to announce me the terrible news.

I have not lost anyone except my dear aunt 2 years ago.
I was conceived when my mother was grieving her mother who committed suicide. Do you think this is linked?

How could I calm down and stop thinking about such tragic things? :( it’s draining and it prevents me from enjoying my life
