I have been trying to learn how to swim (freestyle) also. The technique that has helped me is "total immerission". I heard about it from Tim Ferriss in 4 Hour Body. You can find instructional videos for it on YouTube. It looks so calming, but swimming is a challenge for me! I am interested in Yoga also to improve flexibilty and be more functional. Do you have any suggesstions for videos, or are you just taking classes? I'm sorry that your thyroid problems are still such a big struggle. A doctor/website that I use a lot and recommend is DrAxe.com. He has some great articles on Adrenal fatigue. I don't know if it would be of much benefit to you, but it has been helpful to me for some auto immune and adrenal problems I have suffered from. I really enjoy following your challenges. Good luck!
