First and foremost, I just want to say thank you so much to Patrick McKeown. I am 67 years old and ever since I was 18, I started to suffer with anxiety attacks that were so bad I developed agoraphobia and was afraid to leave my house for almost 10 years. I am still to this day terrified of the body symptoms, the palpitations, the unreality feelings, the lightheaded feelings, jelly legs and feeling a loss of control. But now because of you and all that you are teaching about how the way you breathe makes all the difference, I finally have something that is helping me. I have researched and used all of the resources that you have regarding anxiety and panic and I have a ton of stuff from you and now I have something that can get me through this hard life with all these problems.I also loved the online class for Panic and Anxiety. You covered so much in the 2 hours. And I love having a copy for my records and so I can keep listening over and over and practice.By the way, it is amazing to me how every condition you talk and write about, I have. For example, insomnia, forward head posture, chronic fatigue and on and on, I mean it is fascinating how you know about all these things that I have. No doctor, no psychiatrist, no therapist has ever been able to give me any help. This is why I have to tell everyone how great you are Patrick. I just appreciate you so much. You are such a good person and you care about helping people that are suffering. You are so different than anyone.I started carrying your books, Close Your Mouth and Anxiety Free in my bag wherever I go, in case the symptoms of panic come over me.And on my kindle I have Sleep with Buteyko and on my Audible I have Oxygen Advantage. I look forward to any online class that you will do in the future.Thank you so much.
