People who have been in a gunfight either because of their profession or any other situation, what is it like emotionally and psychologically? What goes or was going through your head during? Is there anything you could do to prepare yourself for it?

No you can’t prepare for it. You can train but nothing prepares you for the real thing. Idk what was going through my head the first time, but over time it’s more like anger, fear and intense stress. Mostly anger for me. Anyone who says they’re not scared is lying
