Puzzling Me

Doesnt it amaze you that at times you just cannot understand yourself?
It does for me.

The things that I want, the way that I behave and feel
are at times puzzling..

I may want one thing, and within minutes or even seconds,
I may not want it at all..

I may be laughing and talking non-stop
and out of the blue, I will cry..I might even just shut myself from the outside world..

I may feel happy or just normal and contented,
the next minute I will feel hatred towards a lot of things..
really, like hate hate..

Now, can you explain that to yours truly?
