I'm kept awake at night by my overwhelming fear of death
Where does this fear come from?
I should ask a psychiatrist.
Fearing death isn't uncommon, but it shouldn't keep you awake every night. You are smart to want to talk to a therapist or doctor, they can help you find a coping mechanism to help your sleep.
I guess I'll talk to one, I just don't want to take meds.
This fear of death is obviously causing you a lot of trouble, and even just talking it out with a doctor will help you to overcome it, probably without any medication.
