Tired

I only managed to get four hours of sleep last night and not from a lack of trying or staying up late. For whatever reason, I lay in bed for hours trying to sleep and just couldn't until past 3 in the morning. Now, I am tired and have a headache like yesterday. Every time I yawn, which is pretty often, my eyes sting. I feel sick and have no idea how on earth I am going to complete my usual daily tasks. I would try to take a nap and get a little more sleep in, but I have a history of simply not being able to fall asleep during the day. We'll just have to see if I am any luckier today. Probably not, but I may as well give it a try.
