What I'm about to describe is hard to generalize, so I'm sorry for the vague title. I came here to ask if seemingly random and innocuous moments cause anyone else to have panic attacks. I'll try to specify more; I had this happen to me a lot over the past few days. Everything will be going fine and then someone will say something and I'll fear this wave of anxiety and urgency rush over me, and I always swear it's something I've heard someone say or do before. It's a sort of  deja vu-induced panic attack. It's a lot more frightening than it sounds. I can't do the experience justice with words.
