Until today, I had a hard time of getting into sleep. Maybe it's time for me to take some sleeping pills, especially since exams is coming near, and there is one problem that I can't get it out of my head. I did promise that this won't be anyone's fault, so I will try to solve this as soon as possible. I don't want it to affect my exams =)
Hopefully I won't get addicted and be a pill-dependent person.
