Tired

So, here I am again.
Awake though I should be asleep.
It is amazingly stupid... I was dead tired today, so I went to bed at 9 pm. However my phone rang at 10 pm and after that I have not been able to fall asleep again.. And you just don´t even know how much I would like to sleep. I am still dead tired, but something just keeps me awake. No matter how hard I try or not try, my brain just won´t shut down. I simply hate it.
I know this will take time again and tomorrow I will be tired the whole day. Hooray!
I just want to sleep, please let me. (It is 11.51 pm.)
