How do you fall asleep?

The question sounds stupid as hell but I genuinely need help with it. Currently it is 2:40 in the morning and I have to wake up at 6:30. I just got off of a 2 week break so my sleeping schedule is shit, and I cant fall asleep at all. I've tried counting sheep, running in place, listening to music, but it's not working. And the thing is, I am 100% tired haha I forgot to sleep the last two nights.
