That is very interesting partyofone. I have OCD. I memory check a lot and have other compulsions to try to tame my thoughts. There are themes to my obsessions. They center around have I hurt someone or have I taken something that was not mine and with a broader theme that I am a bad person. I have not been treated badly by my family in a long time but that was an issue until I was around 25. But I am not sure why that would make one obsessed with death? Is it because you are in a situation so bad that you think of death?
