A solid few months of being sleep-deprived and overworked, and I still do not have the ability to sleep early (it's a Friday, 1.30 am, and I'm not doing anything interesting, but still refuse to go to bed for no explainable reason) nor do I have the ability to rise late.
I always get unnecessarily anxious and twitchy whenever D's not around, and he's gone for the weekend + the past few days. Poo.
