Canyonlad66, Try Fish Oil ( Omega 3 ) 2,000 mg a day. They are the brain function vitamins, work incredibly well as they are excellent for anxiety, depression , ADHD, Alzheimer's. This is the only thing I take for anxiety. They work as well, if not better then SSRI's ( Celexa, Paxil, Zoloft etc..) When my Panic Attacks first surfaced The most prominent symptom for me was also breathing ,caused by hyperventilation syndrome aka shallow breathing. Just begin to do deep breathing..count to 4 slowly inhaling through your nose , deep and rhythmic , hold for a second and then exhale to the same count of 4 slowly through your mouth...continue this, focus. Now the key is not only doing this when you feel anxious. Retrain your breathing, stop and consciously do this during the day at random times. Now I know how scary it feels to be short of breath but the fact is nothing will happen to you. You are throwing the Carbon Dioxide / Oxygen ratio off and that is what is making you light headed and short of breath.The absolute worst thing that would happen is you would faint, YOU WON'T because your brain will send a message to take in more oxygen and regulate your breathing ( hence the grasping that you think is your inability to breathe) So make it easier on yourself and retrain yourself to breathe correctly with the above exercises. Trust me , I not only have hyperventilated and shallow breathe regularly but I actually " hold my breath". So I too practice taking deep cleansing breaths. You will be fine. The Irony of Anxiety is that because of the hyperventilation scaring me sooooo much I quit smoking 30 years ago....SILVER LININGS there are always silver linings in life. You will get better, time and deep breaths that's all. Be Kind To Yourself.
