My cat is not the problem, the sun is the enemy

Opening the door at night started to feel as a sort of ritual even. Needless to say I hate it. I hate open doors with a burning passion. 

But I have a new problem. I can't sleep well. And what happens when I can't sleep well is that I get sick. And I can't afford to get sick. 

And why can't I sleep? Because of the sun. It shines through my window like some happy egocentric optimistic little fuck so I have to wake up an hour before my alarm everyday. There are days when I don't even set up one, I know I will wake up before it. Luckily time change is next week so I hope it will get better.
