I have never been so tired after an 18 hour day before. I don't know if it is the continuing chaos of our ever changing schedule, waking up early for a full 5 days in a row, two late nights of studying earlier in the week, the last two twelve hour days at school, running all over the school and then the city today or the incredibly exciting/stressful experience of talking to actual patients this afternoon. We had our first clinical correlation today and saw two people with different blood diseases. It was great to actually see people and not just cases for a change. I am going to bed now.
