Do you often feel your mental tiredness convert into physical tiredness?

Not sure if it's tiredness, but definitely it can translate into a sense of the inability/unwillingness to actually do anything.

Yes. The mind and body are connected.

Yes often because my job is mentally stressful.

I find that even a short walk around the block helps me immensely in getting a little bit of energy back

Yes, exhaustion of the mind can definitely cause physical fatigue.

Yes

Every. Single. Day.

Nope, never

YUP!

All the time. When i am anxious, my shoulders hurt as hell. I feel powerless and exhausted.

All the time
