Hi Jen,
Thank you for sharing your story with us and welcome to the Panic Center Support Group. You said you are not sure if your hormones because of breast feeding are causing your anxiety / panic attacks to return, this is definitely something to discuss with your doctor on your next visit.
Have you had a chance to take a look through the Toolbox? There are many supportive tests, which are not daignostic tools, or a replacement for a doctor's advice, but they are there to prepare you with information which you can bring to your next doctor's visit.
There's also a Panic Program available for you. This program is 12-weeks and it is designed to help you better understand your anxiety/panic and give you some ideas on how to deal wtih it. Each session is based on the previous session, so we strongly advise that you work slowly through the program and not jump ahead.
These tests may or may not be for you but they are "free". If you have any question or concerns about the things in your "Toolbox" you can contact us at support@paniccenter.net.
Also, do read through the posts of others on this forum, as they may share the same concerns and have the same questions you do.
