Something wrong with my brain

You know what? Recently, I suddenly really happy, suddenly really sad, suddenly really cold to my friend although they don't notice it. I'm not dislike my friends, sometimes I just don't want to talk too much, feel tired. Weird.

As my brain's owner, I have to find out the problem. What made my brain and my emotion become weirder and weirder? PMR? Maybe a bit. Homework? I don't think so, and I'm a good student as well.

Anyway, I feel that I am tension and nervous and maybe having a psychology problem call depression. When I told my classmate this afternoon, she put her hand on my shoulder, and looked into my eyes, and said the sentence below:

"You, Rain, will never have this psychology problem forever unless the Sun rises from the west."

"......"This is my answer. Okay, I admit that I'm this kind of people.

Today is April Fool, my school was in a kind of crazy situation. Many people shouting and scolding someone. Luckily I am alive from school.><
