Hi Hunter and welcome!
I agree with Hibee about
talking with your doctor regarding possible treatment for your panic attacks...there is hope and help, and you need not suffer these!
For now, I am going to post some links from the Resources that should help you very much. Practice the ones you think look the best for you everyday. They will lower overall stress levels, and physical symptoms.:)
