Okay first things first you shouldn’t do buteyko without clean bill of health. Get your check done for heart. Once your doctor says all clear. Then you can truly accept anxiety. Your general doctor may even diagnose you directly with anxiety. Mine eventually did (for anyone doubtful it took me 6 months after this to actually even believe it to be anxiety). Theanxietyparadox on Instagram is the greatest. Everyone reading this just think about anxiety this way. What is anxiety? It’s not being afraid. It’s not having mental battles or whatever. It’s an incorrect relationship with your thoughts feelings and sensations. Your heart thumps loud skips a beat, a sufferer will try control that prevent that resist that, a person who doesn’t suffer with anxiety shrugs knows they can’t stop what their body produces. So In this same manner when you all (I suspect many) that come to this forum, when you truly treat this awful feeling as nothing, refocus on what you can control(i.e your actions in life) and just surrender fully. You become slowly normal again. But this is the key thing and why it’s a paradox and why you all get stuck. The more you try to “get” better(stop the feeling being noticed) the worse you will get. So your goal is not losing symptom if it is your goal that’ll never happen. Your goal is life. When you wake up everyday your goal should be to be indifferent to this, you may not like it but it is coming with you you know you can’t control it so WHY BOTHER TO TRY AND CONTROL IT.
Thing is, someone like me now I don’t care if it came back tomorrow and that’s the reason why I’m recovered. You don’t use this as a tool to rid it. You genuinely see you can live a happy day if you don’t let it affect you. And the fact you are indifferent to it then it doesn’t even matter if it is there. But as I said your goal is life. In my opinion, buteyko or supplements or diet changes, whatever is against this acceptance. To fully benefit you can’t do both because you have to show unimportance. You can’t show it if you’re dedicating time to buteyko or whatever. I did buteyko once upon a time. My symptoms subsided for a bit due to the fact I forced myself to go into college every day and symptoms decreased tremendously same time I started buteyko so it got the credit unfortunately. The people who still believe it to have fixed their problem imo are holding on to a similar scenario. They want to be in control they want to have a tool to fix it. They can’t accept the lack of control that they are at the mercy of whatever thought or feeling or sensation their body finds. That’s just my opinion. No hate all love everybody. Hope you all start living life happy.

No problem and let me know how things go. Also let me know if you have any questions on the breathing exercises or any pointers I can give you. I stuck with it for a few weeks and it did wonders for me, so I'm hoping you see results soon.
