@XOIIO Obviously she can’t sleep, why not try a different approach to answering this?
It’s good that you’re seeing your psychologist. My boyfriend had bad insomnia last summer, it’s tough. In his case, it was caused by stress since he’s the boss of his company and had a lot that needed to get done. The electronics thing is good, also quit caffeine! In general, avoid putting anything in your body before bed since you can’t quite fully relax while you’re digesting, and if you miraculously do fall asleep you don’t want to be awakened by a beckoning bladder!
What finally helped my guy was marijuana and lots of stretching and yoga. The nights he smoked/ingested before bed, he was able to fall asleep, even if it didn’t last all night (I say ingested because he spared his lungs by making a batch of weed butter, used to make brownies and such, then just ate a bit in a teaspoon of honey).
Also, having stretching/breathing/meditation sessions throughout the day (morning, lunch, and bedtime) helped a lot.
The last thing I recommend is trying to fall asleep without actually trying to fall asleep. So not just “laying there not doing anything.” That’s when you’ll get frustrated about not sleeping, which will just stimulate you further. Back in your days of sleeping did you fall asleep during movies? Cuddle up on the sofa with a blanket and put a long boring movie on. Stay on the sofa! In general, sometimes a change of scenery does help; I’ve passed nights on the sofa during periods of insomnia.
Just kidding, THIS is the last thing: if it is stress/worry that’s keeping you up, try this technique when you’re trying to sleep: focus on something that worrying you. Then blow it out of your brain like extinguishing a fire. I will actually make a blowing sound when I do it. That thought is hereby banished. Do it with as many stressful thoughts as you have. Be diligent about not letting them back in! Sounds crazy, but you have more control than you think.
Similarly, I’ve noticed that I can pinpoint what part of my brain is activated when my mind is racing. When I remind myself to forgot those things and clear my mind, I can actually feel the “cursor” in my brain slide to the front, right to the top of my forehead. Bring your mind back to the present, and I bet you’ll notice this sensation. Try to keep it there (I like the computer cursor metaphor), and focus on breathing.
I know this doesn’t answer the question about what will happen to you without sleep, but I hope it helps!
