I'm sorry. I didn't mean to be like that. I don't know why... but I just feel so down. I can't find the specific thing that makes me feel like that. I think guilt is one of them. I'm feeling guilty that I haven't been to visit her for 3 months. I think the main reason is I think too much. Worry too much for others. I just wish that I'm not such a sensative person. But I can't help it. I have no choice. I hope I won't have sleepless night anymore... cause it cause me to feel lousy.
