Hi B and welcome!
I am sorry to hear of your current panic, symptoms and struggles with anxiety.
Have you talked with your doctor about
possible treatment options yet? Medication and/or therapy have helped many people dealing with the same challenges you describe.
Merrida recommended our Resources for self-help, and I think that is a great place to find many helpful coping skills, information and all around good material as well.
Here are some of the really beneficial anxiety management exercises that you could get started on right away.:)
