exhausted

I got about five hours of sleep last night, due to the incredible amount of procrastination achieved this past weekend. I had a ton of work to do. Two projects, multiple pages of math homework, and several chapters of econ to read. Of course I saved it all for Sunday night. I didn't plan to save it all for Sunday night, but a lot of unexpected things happened this weekend.
I planned on spending Saturday night and the whole Sunday day working on my homework. But on Saturday my mom had called me to make arrangements to go to a dinner party with her. I didn't have any other plans, so I was in a way obligated to go. So that's how I spent my Saturday night. I was so exhausted by the time I had gotten home from the party, and so as soon as I got home I took a shower and went straight to sleep. I didn't bother to start any of my homework, and figured that the entire Sunday would be enough time to start and finish my homework. At around 9:30 am, my manager from work called and told me that I was suppose to start work at 9 am. I had checked my work schedule on Friday, and it was blank. Work schedules are supposed to be done every Thursday,but there were unusual circumstances at the work place, so the schedule was done late Friday night. So it wasn't my fault that I didn't know I had to work. But anyway, there went my entire Sunday day.
By the time I had arrived home from work, it was already late in the afternoon, and I had not even begun to touch my homework. I took a shower to prepare myself for a looooonggggg night of homework. I was not looking forward to starting my homework. I finally finished my homework at around 1:30 am, thus, I only got five hours of sleep.
As a result of lack of sleep, I had a really bad headache this morning and found it very difficult to concentrate and sit through my morning classes. I nearly fell asleep in all of them. But tonight is going to be a similar night to last night because I have an economics quiz and a math test tommorow. Plus, 24 is on tonight and I absolutely cannot miss it. I'm very hooked on the show and I could not go a Monday night without watching it. I also got my hair cut this afternoon, which took up more of my time to study. Tommorow is going to be a long day...and I am utterly exhausted. I don't know how I'm going to survive this week if it is starting off the way it is. Gah!
