Can't sleep, can't write

It's been few days after my last blog. Everytime I typed something, I wandered away from the topic of discussion and end up feeling the article was crap and deleted them. This happened again and again, the latest one is 5 minutes ago. Maybe I'm pushing myself too hard to write? Or my brain just couldn't think right? Or I just need extra sleep now?

My mind was so occupied with a lot of things for the last few days. My girlfriend, my studies, my family, my assignments, my classes, my society, my lunch, everything. I end up feeling drained and resort to sleep. The problem was, I was't sleeping at the right time. When I'm writing this blog it is 5.30am and I haven't slept since yesterday. But I did slept from 2pm to 8.30pm. What's wrong with me?

Maybe I watched too much House?
