Hi Arghhelp,
I know your frustrations!! I know how scary and temporarily uncomfortable it can be. And sometimes as we get 'over tired' sleep becomes more difficult because its like our system is out of whack. Add on the extra anxiety and bam, pretty frustrating situation.
Two years ago something similar happened to me. I was so frustrated that I did end up going to the ER in the first time in decades. But the doctor calmed my fears, gave me an antianxiety med that he took occasionally to sleep because he works the night shift. I took the med, calmed down, and sure enough I eventually went to sleep after not having slept more than 3 hours in 3 days, and I got something like 6 hours of sleep that night, and woke up feeling much more relief.
Your body will eventually go to sleep, whether with the help of a med or just naturally on its own. Its a temporary burden and extremely uncomfortable to be sleep deprived, but it will get better.
The issue with anxiety is that it is sort of the "anti-sleep". I was reading some sort of medical article about sleep and I remember it talking about the fact that we are adapted to use fear as a means of survival. When we get anxious, its the mind and body's way of saying, "be on the lookout. You need to exercise caution. Stay alert!" so the brain is actually wired not to sleep when in a state of anxiety, as sleeping with a threat present would be leaving us exposed and in danger of being a target as we are vulnerable when we sleep. So for those of us with strong anxiety reactions, we may find sleep more difficult from time to time. But it all comes down to the basics of biology and survival.
I don't know if that helps you ^ but I sometimes find solace in understanding the mechanics of how the human mind and body work.
Anyway, just keep in mind that this is temporary, you WILL be okay. I was okay even though I was so nervous when I couldn't sleep those few days, but here I am, I survived, and you will too!
Tips:
When the worrisome thoughts come into your mind, speak reality outloud to respond to them, you can say:
"Because of my anxiety, I have had trouble getting to sleep. Now I'm over-tired, which is also making sleep more difficult. But this is a temporary issue and it will be resolved. This has happened to other people but they were okay eventually. I will be too."
Take a warm bath before bed (body temperature dropping helps us sleep)
This is a trick I use sometimes: When you are in bed, visualize warm childhood memories of places you used to visit but are somewhat vague in your mind. Visualize a home of a friend's house, each room, try to recall each detail. What was was on the wall? What was the color of the carpet? Try to walk into each room. What is the furniture like? I try to recall the details of elementary school my best friend's house, any building I used to visit that I have not in a long time. I find this takes my attention off of the fact I can't sleep and relaxes me and even if I don't sleep, it at least keeps my mind occupied, but usually I do fall asleep.
***************
I know you don't want to go to the ER, but I don't regret going when I went, because it was the one thing that really did help me get that rest I needed. So maybe if you are still having trouble, call a doctor, or maybe urgent care or last resort ER if you really feel you need a little more help. Though who knows you may fall asleep tonight naturally.
Feel better soon. I'm sending thoughts of zzzz's your way.
