The anxiety forum on Medhelp has some pretty good suggestions. Might be worth checking it out here - http://www.medhelp.org/posts/Anxiety/tips-on-dealling-with-panic-attacks/show/1485566#post_6752037
As far as taking ADHD meds to help. It depends if the anxiety is a side result of ADHD. In,
"The ADD/ ADHD Answer book," by Susan Ashley, she states that 25 to 30% of children with ADHD have an anxiety disorder. I think it could be higher in adults. So its possible that dealing with the ADHD would help. I think the answer does deal in coping or learning how to live with ADHD. There are a lot of resources out there to help you - including medicine choices. My own feeling is to go with a short acting one so that it can be taken on an as needed basis (if possible). But the important thing is to find a doctor that will listen to you. All meds are kind of done on a trial and error basis. You need to experiment until you find what works. To do that you need a doctor that will be an experienced, informative, communicative guide. At any rate, your doctor should prescribe what he/she has experience with using with their patients.
By the way, here are some good videos on anxiety from a pretty good adult ADD site.
Please post if I can be of any more help. Best wishes
