Exhausted

When one's exhausted, even the simplest question takes ages to solve. I wonder why this evening I'm so tired. Physically and mentally. What's worse is you can't find a proper and cosy place to rest...not even your home.. That moronic bitch keeps thinking that the room is solely hers and use it as she likes. Living room is full of wooden planks and siting on it for hours is no joke. Resulting achy backs and bums. No place for me to lie, if this goes on, I would probably be declared mad.

Wed is my first prelim paper and I don't even know what I have been studying for the past weeks. No not low confidence.

God, please help me!
