Excessive Yawning and Constant Need to Breathe Deep

Does any body else get chest pains with this 

Well I have tried almost everything now so fed up of feeling like I can't breath properly I'm even worried about sleeping just in case I can't breath is this just me. I'm on my last resort I am now trying a chiropractor 

I am recently suffering from shortness of breath and the need to yawn.  I have to think about breathing instead of it being automatic!!  ..feel I cant fill my lungs, the more I think about it the worse it gets.  Iam on medication for hypertension and atrial fibrillation  and two of the drugs say the side effects can cause shortness of breath, so this might be it.  Recently had an angiogram and I have no blockages.  It is not a problem when I do water aerobics, seems worse when Iam not doing anything, probably thinking nabout it too much. 

I aslo have recently been suffering with similar conditions. Does anybody else expeience mild heart palpitations, headaches, and lightheadedness with this sometimes? I honestly believe that we are all just constantly hyperventilating from the stress and anxiety we put on ourselves. We are all just stuck in this bad habit of breathing in too much and too fast, and we're constantly thinking and worrying about it that it never gets any better. I think that the real problem, for most of us atleast, is that we simply are just too anxious of all these symptons. In the moments when im doing something and my awareness is somewhere else completly, I notice that my breathing slows down and i feel a bit more realaxed. But then I go right back to thinking about my breathing, and get all anxious again. When you're constantly worrying about your breathing and you're always consciously trying to breathe, you make it only worse. It's all just anxiety. For example, when you're in a healthy state, you go all day without never thinking about you're breathing. Your breathing is slow and easy and no forced, but in a anxious state you start hyperventilating,and then you get more scared because your'e now hyperventilating. It's a vicious circle. I think learning to accept this will help you let go and eventually get better. Also slowly implemting the Buteyko Method that Will mentioned should help alot with regaining that normal brathing pattern.
