Insomnia is back.

I have laid here for hours feeling very tired but sleep just isn’t happening. I swear that my brain refuses to function properly. I took an hour in the bath when I got home tonight. I lost track of time for a while. How can you feel like only 5 minutes has gone passed when it has been a complete hour? I feel weak and sick. I had a small drink of alcohol to chill out while finishing some of my uni modules. That wasn’t a good idea. I feel so far away. I hear and see everything around me but it feels all unreal.
