It's just me in my own head

If there's a problem then go and fix itIt's such a simple phrase but I can't grasp itI lay awake at nightWith the fear of dying if I close my eyesWhat's the point of existenceWith this incurable sicknessJust show me the doorGive me a place to restWhat I would give to sleep my life awayI'd never feel alone againAnd yet it's still the same when I'm dreamingCause at the end of the day it's just me in my own head
