I think it's hard when the people and situations that trigger you are ones you have to be exposed to every day and just can't avoid. That's how it is for me. I try to just slog on through as best I can. It would be impossible to avoid these triggers, I would just end up being a hermit and not having a family or friends. I need to work on the root issues so that I can resolve those triggers so they don't trigger me anymore. Sometimes maybe it can help by acknowledging the trigger to the person involved. Like, "I hear what you are saying, but it reminds me of all the times you did X, and I'm struggling with that because those other times were so upsetting." It can help if they give reassurance, but they usually don't. I don't know if it's helpful for me to say that to them or not. I'm trying to find my way.
