I couldn’t sleep again … annoyed at myself!

I’m tired but wasn’t able to sleep again. I need to change my bedding because my allergies are so bad at the moment. I’m uncomfortable which has kept me awake. I am really annoyed at myself for not sleeping. I’m that tired its literally painful to be awake. I don understand why I wasn’t able to just sleep. It’s a simple thing but so hard to do. I walked a lot yesterday so my bad ankle is aching which isn’t helping. I feel like someone has punched me in the eyes because I’m that tired.
