i have been abusing sleep meds to keep myself at that stage of exhaustion for years now. not for sleep necessarily, just the ungodly amount of fatigue that comes with taking large doses. sleep is scary because you can dream anything while you're out, even shit that you should never witness (had a dream i watched my mom get shot), so i keep myself at its border.
it is miserable and my head feels like there is a campfire in the middle of it, but at the very least i'm not thinking about him all the time anymore.
