Who am I?

What had happened to Chai Yee Wan these days?
She always put herself in a bad mood recently. Is there something bothering her? Can someone help her to figure out what's wrong with her? =(
She is mentally unbalanced! She's unhappy!!! She wants to distance herself from others. I want to bang wall now! 

Capricious.

I''m so sad for you because you have a capricious girlfriend. :(

Really.

I think you're the one walking further from me.
