Insomnia?

Ever had one of those nights when you’re extremely tired & just want to go to sleep, but once you lay down on that comfortable bed of yours it may seem as if your brain/mind just doesn’t stop thinking?! Like it wouldn’t shut the fuck up & rest for the night?! Yeah. I’ve been experiencing that shit for a few days now. I have no clue why. Am I just too excited about something that I don’t even know about?! Or maybe I just have issues. Whatever it is, hopefully I can get back to my old sleeping pattern soon.
