Drained

What am I doing here in the middle of the night? Here I am snacking away on potato chips (from my brother) as I'm trying to finish a report. Not bcos I'm hungry but I'm trying to keep myself awake. Feel so drained out now. Was it due to incompentency that I have to work late into the night? This was the question that first come into my mind. Seriously, I do not have an answer to this. But right now, I think I just need a break, a holiday or something.
