After my first couple of anxiety/panic attacks in elementary school I don’t remember experiencing many or any for a long time. In college, they really took off. I had a few my freshman year. They were limited because I shared a room and I just didn’t, maybe refused to, have them in public or in the presence of anyone else. After that year, I’ve always had my own private bedroom. And the frequency and severity of attacks soared to new heights. I had them while driving. I ducked into bathrooms to have them. Each year got substantially worse than the last. They only started to decrease to a rarity 2-3 years ago.
