That happened to me, I was fine, I got on the bus went out, and I was just about to get off and I got a panic attack, I pretty much sat with my husband on the phone for 20 mins and then got the bus home.
It was awful, it came out of nowhere, but I was also talking with the bus driver about how I just quit my old job, and I think I was getting worked up, and may have triggered it.
