Hi, I used to suffer from panic attacks, and unhelpful as it is, there was never a generic way of dealing with it. As a general rule I would hate for my gf to act any different when we were out in public as I would feel as though talking about it or doing anything about it would attract attention (even though that was probably in my head).
In any other situation just go with the flow. Sometimes it helped talking to her, taking the focus away from the panic, other times talking would just be almost an irritation (not just with her but with anyone) and id just want a glass of water and a bit of ***** to focus on my breathing or other techniques that I found helped.
To be honest though, I would talk to her about the panic attacks at times when I wasnt having them, I think that helped her a bit, and may have been a help to me, its difficult to tell.
It might be a bit difficult to understand, but having panic attacks, as a guy, is a humiliating in a way, so try not to get upset or annoyed if he doesnt want to talk about it (im not saying that you would, but its easy to see why a gf or wife could get upset that their partner doesnt want to talk about something personal like that).
All I can say is that the more the occur the easier they are to deal with, it will get better in time.
Also, if the 1988 part of your alias is your birth year then we are about the same age, dont know if that makes what I am saying a bit more meaningful or not...
