Insomnia

I have been awake this entire night. Not even a short nap. I have a headache from trying to sleep. Such a pain, literally. I have a meeting at 10am with the bosses, the UK ones, and I know it's all because of this that I have not been able to sleep. I am a little worried that I am going to be fired. I know I am actively looking for another job and have had an interview but I would like to leave on good terms. If possible.
