What do you call someone who is obsessed with death?

Since i was a child i always thought about death, my father was 53 when i was born he had cancer and was very ill, so everyday i would look in his room and wonder "is he dead" and i would think about what will happen when he dies and the funeral, This went on for about 7 years when he did die and i had a nervous breakdown and went to therapy as a result.

Now I'm focusing on my Mom, shes getting old, 72. Shes in perfect health and still working.. Everyday i think about how and when will she die, if she forgets to call me i think shes dead or in an accident. If her friends call i think their calling to say shes dead. I think about her funeral, who will i invite, how should i dress her.

My cat is 16 now, everyday i think "is this the last"? she is in perfect health too. I worry how and when will the cat die, I take photos just in case she dies soon. I think about it everyday.

Also if my brother is late, i think right away maybe he killed.

Whats wrong with me?
