Hi, welcome
Being obsessed with any topic is a concern. The balance needs to be restored and that is generally done by a therapist/psychologist.
You aren't alone, paranoia hit me many years ago. My therapist told me my thoughts aren't realistic and introduced me to ways to assist myself.
Anxiety played a large part so relaxation techniques were learned. Asking myself "is that thought/fear real or not...if not seek a distraction to discount it and so on.
Life is complex and death, sadly, is part of life. But over analysis of death is robbing you of living.
So, I suggest you visit your GP and ask for a referal, this can be resolved.
Well done in writing in.
