Who else can't sleep ??

I get so tired and exhausted but when I close my eyes I can't seem to fall asleep 🙄 I lay on my back and I can't breathe. I lay on my stomach and I and uncomfortable. I lay on my side and my shoulders hurt . So when I finally do fall asleep (3 hours of laying in bed tired and hoping I get to sleep) I toss and turn thru the entire night ! And of course I wake up at 5 in the morning because I'm uncomfortable and can't sleep anymore ☹️I'm so exhausted!! (Sorry for complaining lol) does anyone know anything that can help me sleep ? I'm desperate and tired (if I haven't mentioned that enough lol)
