I have never felt this way to be honest.
But you are right. I am feeling disheartened at the moment. Or rather, like a starfish in a tide pool. Brainless, directionless, and with surroundings that are rapidly becoming unbearable.
Quoting: pi I hear you...
Do you feel a product of circumstance?
How do fate and freewill dance?
You are certainly not 'brainless'.
Immensely talented you are.
Rest assured that others recognize this.

Also, you may have a bit of shell-shock. It happens on GLP.
That is why I avoid ALL doom threads.
Point your focus toward that which brings you and all those you care about, back to center.
Ignore they who cause you imbalance, unless you are certain to be 'unmovable' in said situations.
I hope this helps...
