I am so terrified by the thought of dying I think about anersyums, brain tumors, & heart problems. I've been mostly worried about brain problems lately because I've been getting sharp pains in my head. I thinkwhat scares me the most is the thought of never existing and the pain. How can I overcome this please??? I am very depressed thinking about it and looking it up all the time too. I stay in bed and don't want to talk to anybody. Its really got me messed up. Please can someone tell me what I should do to help myself?
