Yes. I have anxiety issues, AND, have had to fight a LOT. Before, or after, a fight, my limbs STILL shake sometimes. Anger, is part of it. I assumed that the shaking, would eventually stop, as these things were more commonplace. Doesn’t seem to matter. I think, we just naturally get upset, about things we don’t like doing. I wager, a mass killer, doesn’t have shaking hands. Because it’s not something that they are opposed to. Just my opinion.
