Last night I wasn't able to sleep so I'm more than 24 hours awake and for some reason being sleep deprived has given me some kind of huge anxiety like I can't relax and close my eyes to sleep now, I'm having some kind of weird fears like I won't be able to fall asleep and I'm gonna start hallucinating from lack of sleep or something lol. 

Do you have any tips how to fall asleep quick, has anyone been in this situation from lack of sleep? I should just eventually get a big urge to sleep and that will be it I guess?

I don't usually have any anxiety, only when sleep deprived and it's horrible lol.
