EXTREMELY bad insomnia

D
So I've always struggled with being an insomniac but it's NEVER been this bad. I usually have insomnia on my period but I just ended yesterday and I didn't have insomnia this time, however after I do, extremely bad. I was laying in bed trying to fall asleep for about 7 hours which resulted in an all nighter and I fell asleep for like an hour and am wide awake and idk how to deal with it honestly. I don't have any melatonin or anything in the house right now so I can't use anything. I just need help bc I have never been so tired but not being able to sleep :(
