Learn to hold your breath in the water before you can start with the best breaststroke. It is very important to learn to breathe first in the water. Breaststroke is easy to learn. You can rest your head on the water. The most important thing is the coordination of hands and feet. I don't remember the posture of my hand, and I forget how to stroke my feet.
Hmm. How interesting
Swimming is a science. Learn it well and continue to learn backstroke, freestyle and butterfly. Everyone is from being afraid of water to being afraid of water, and then to being a master at swimming pools. Don't be afraid, be brave.
Wish you success!
