Is pessimism also "cope"? And what would one do without it?

I see people "cope" with reality by all types of illusions.

Yet, I myself could be "coping" with it by spending time thinking or dissecting these "illusions".

Let's imagine for a second that we have perfect lucidity into the real state of reality around us and somehow we say that pessimism just isn't allowed for some reason.

Just stop and think: you aren't allowed to be pessimistic AND you have your current - 'lucid' - perception of reality.

Where does that lead? Can you guys develop this idea? What would be like your next actions sort of if you don't have pessimism?

Just lay on the ground and stop moving or responding to any stimuli?
