Everything is a blessing, but can the worst get any worse?

It's so hard sometimes..

At first you succeed in believing that everything's a blessing, and that even the worst can only get better.
True enough, things have been looking up for you. For a while, nothing can be more powerful than a healthy, positive mentality.
But then later you realise - to your dismay - that all this while, discontent has been accumulating. It had actually found its place somewhere deep within you, eating away at your cardiac walls.
Eventually - as it builds up to a weight your optimism can not carry - it forces its way out of your heart and into your veins - flooding your mind, choking your senses.

What have you done?
You don't know.

What has become of you?
...

Who are you?

Thoughts flutter through your mind and fly away, desserting you. What's going on?
Suddenly there are questions begging to be answered - the answers to which you do not know.
Suddenly you don't even know who you are.

All you know is that suddenly, you wish you were anyone but you.
