My cousin has been dead for four years. Why do I still don't believe that he has passed away? It feels so fake. Why?

It's been four years since your cousin died, and you haven't forgotten your grief. It shows that you are a sentimental person, which is also an advantage. But I want to advise you that you must face the reality. My cousin is dead and can't be resurrected. If you miss him too much, it will affect your physical and mental health. Frowning all day, unhappy, can my cousin's soul be at ease?
