Recently my cousin has been acting weird. At first I thought he was joking or just going through a phase , but its been about 2 months now.

He always says things like "Im already dead, im living in a coma that ill never wake up from (Not exact words, but what i remember)". After a while i realized he was being serious. He can't even any movie or show that involves death, otherwise he starts crying that he is dead as well.
