Since the last comment I wrote in here, I swam after missing a week and a half. First thing I noticed that my anxiousness or nervousness had subsided I also felt a little confident where I left off. I finally got to a point in my threading that all I have to do is tilt my head back- using the back of my head- to hold my head over water without using sculling and moving my legs/feet. In other words, like a vertical float. The second improvement is my breathing. Since I’m less fearful, my apprehension to blow out CO2 or exhale underwater is subsiding and I’m actually inhaling and exhaling air through my nose. I think again feeling more comfortable in the water. Hope this helps,Caribe Community.
