How do I carry what I've seen from a high voltage accident?

You can work high voltage safely on instinct now, and part of why is that you have seen what happens when someone could not. That is a heavy thing to carry. The memory of an accident, of what electricity does to a person who made one wrong move, does not leave. It rides along on every job. That weight is the price of knowing, and it is real. Carry it as a teacher, not just a wound. What you saw is exactly why you are careful, why your instincts are sharp, why you will likely never be the next story. The people who work most safely are often the ones who have witnessed the cost up close. Your memory is not only a burden; it is part of what keeps you and the people around you alive. Let it have that meaning. When the memory surfaces, let it remind you why the discipline matters, then bring yourself back to the task in front of you. And do not carry it entirely alone; if it sits too heavy, say it out loud to someone. What you saw mattered. Let it protect people now, including you.
