Candy, I sure understand about triggers...and think this is a good topic, but please remember that if you don't receive many responses here (though I hope you do) that when someone here as a member doesn't feel safe, it might be too much for them to tell what triggers them, in case a foe afoot tries to use that against them here... (not allowed but does happen.)
However, I will share my two huge triggers...both because I was injured in a thundestorm and the authorities did nothing to help me. So, thunderstorms and authority not doing what they "should."
