I know there is a link between PTSD and insomnia but I am trying to determine how much of my 7-day insomnia streak is PTSD and how much is me just being a light sleeper. Basically, the person I am currently sharing a room with makes noise all throughout the night -- first by using a hair dryer while I'm trying to sleep, then by snoring or just playing with her phone. It usually starts out where I feel like I'm about to fall asleep but am then disturbed by some sound she is making, so I end up starting the process all over again, with no luck. This happens repeatedly, and then I just lie there for the entire night, unable to shut down. I have tried sleeping pills and even those do not help. I have gotten about one hour of sleep each night for the past week. I don't know how I am still functioning, but I barely am. i end up shaking and feeling sick all throughout the day. Even when I've found myself stuck sleeping near snorers before, I've generally been able to eventually block it out and get at least 4 hours. But now it just seems hopeless. If I go another day with no sleep, I fear I will have a breakdown. At the very least, I will have to abruptly quit this job just to be able to go home and sleep, and then I won't have money to survive on. Has anybody else ever had a similar sleep situation?
