It’s unusual to be so upset about the death of someone you hardly knew. It’s not the norm. It could be something about his death that is upsetting you. Perhaps it is triggering a fear about your mortality or dying young. Based upon so little information, I can only speculate. Certainly, there is more to the story.
This issue requires deeper investigation. I would encourage you to discuss it with a therapist. Right now, it’s a mystery but a therapist might uncover what underlies your unusual emotional response. You may only need a few sessions to correct this issue and it’s certainly worth the effort. Good luck and please take care.
