Hi Mixxer...Im not sure of your age but I myself am 24 now and my attacks started exactly 2 years ago. I will tell you from my little experience what may help.
1. Seek therapy from a psycologist not just a clinician.
2. Walking is huge. I go for about a 2 mile walk each evening and things just come in to your head and leave.
3. When you breathe..put one hand on your chest and one hand on your stomach. Take deap breaths and make sure that your stomach is where you are breathing into. When you breathe deep down into the diaphram oxygen is sent out to all your muscles and blood cells keeping you from getting dizzy and having the shortness of breath feeling.
4. Church and Prayer. I was raised catholic but I tell you I never really was a "24/7 church person". But I think 99% of the people in this forum pray that the anxiety and attacks will just go away. I feel so good when I leave church that it is amazing.
5. Positive thinking. Encourage yourself and encourage others.
I hope some of these things help as I have felt so much better practicing with them. You will feel better and get through it if you believe in yourself!
You can do it!!
Joe
