I am scared to go to sleep because i'm afraid that ill die . why is that.? i feel okay to sleep when i'm around someone.

See therapist: Not uncommon after a loss of loved one / recent significant illness or injury/ major stress. Usually best helped by counseling to help id and understand source (which helps resolve it).

Agree w Dr. Alves: Do you have difficulty in general when you are by yourself? Are you afraid of dying in a specific manner (attack, medical cause, etc.)? There is not a way to tell you why you are this way with the available information. Encourage you to see a psychologist or therapist to address this issue.
