@filmfreak75 that's a tough one. Obviously, some people you cannot avoid. Prepare yourself beforehand - talking to a trusted (!) person about the original incident & what seeing that person again does may be helpful. A therapist might be able to offer helpful ways to reframe the incident in your mind. Yes it happened. Your response is not unreasonable: you're trying to protect yourself. Find strategies that give you a sense of safety when you do have to interact.
