No sleep, annoyed AF

So two days before my period, I CANNOT sleep because I CONSTANTLY feel like I’m about to pee on myself every time I lay down. Now, if I was just not sleeping, I would be fine, but this is legitimately uncomfortable (imagine a long car ride and having to hold it for 2 hours because there’s a long stretch of nothing but sketchiness). I cannot sit still, it only lessens when sitting up but never completely goes away, and NOTHING helps. Any suggestions to relieve this?
