In reply to Removed User:
I wouldn't know about the phobia aspect, but having dealt with panic attacks and anxiety during my 20's ( I struggled to leave the family home during the day at one stage), I guess an approach which doesn't say 'See it was all about nothing' once any anxiety attack has passed would be a good one. It could help (I'm sure you are already) if you created an atmosphere where she felt able to talk openly about what it feels like, too. Try not to be anxious about her being anxious, and give the impression that you know she'll get to be okay again, even if you may sometimes occasionally doubt it, like I'm sure my parents did at times. I always felt secure, so I guess they didn't let on about that.
My Dad has often taken the probably quite English approach of sprinkling humour into conversations about anything serious, which has meant I could talk about something quite 'heavy' one minute, and then switch moods if I've wanted to, and any seriousness has been dispelled if I've wanted it to be.
Try and create a comfortable atmosphere where she doesn't feel like she's any kind of burden I guess, and make sure she feels valid (that her fears are valid just because she's experiencing them, even if they 'don't exist' in the real world), rather than weird or not valid for having them. If you've a network of family friends who she knows, and social gatherings you can all go to, where they can be aware of what she's going through, and accommodate her towards letting her have space to be anxious in before rejoining people, that could help towards stopping her from feeling isolated, especially if any of their children are her friends as well, but any network is helpful I would think.
I was much older than your daughter is when I had my anxiety problems and panic attacks, but I found the network of family friends I have who go back to childhood to be very beneficial. If I have any more thoughts I'll post them.
Hopefully this is just a phase for her, and that it eventually makes her mentally stronger like I think it did do for me. Or not too eventually, in her case. I can banish annoying tunes at will now, which I couldn't do before.
