Hello TinTin
Well, for me it was easy...I get anxiety and panic when in crowds, where I feel like I can't escape. I can even tell you when it started, as a child when I was scared in a large crowd. My best advice is to after it happens write down everything that you can think of all the details that can help you make connections. There's a diary you can use with this webiste...so you can use that to keep track.
