Girls, hi. Help please, I'm already exhausted. To bed 9 days, but I can't sleep. I fall asleep fine at first, but as soon as I get up to go to the bathroom once, everything goes wrong, I can't fall back asleep, even more than 1 minute I can't lie down in one position, like nervousness starts, leg fatigue is some kind of. I can't put my body comfortably to sleep with one word. There's no strength left from lack of sleep?
