Aloha Kev5,
You're doing wonderfully, despite her eye rolling. 
The "feeling" that you've pulled out all the excess energy may take some time to become sensitive to. Before you start the sword fingers, rub your palms together for about 15 seconds, then sword finger and remover the excess energy.
You don't need to put yourself at an angle to miss the heart. Your intention and focus is what guides the energy the energy to the lungs and that's it. That's why one can also sword finger their kidneys from the front of their body, rather than twisting their arms and hands in an awkward position behind them.
The level 2 course will take this into more depth and is worth the investment.
You can show your daughter the Breathing of the Universe exercise with you, or by herself when she feels the tightening or shortness of breath. She can even do this in school by visualizing the hands moving and the energy coming in and out of the body.
Much Love, Shawn
