I can totally relate to this horrible "Breathing Tic", my son who is 15 now started this tic in 7th grade. It was so scary, he could not do anything but try and breath. Every 3 to 4 second 24/7 he would gasp in for air. I would stay awake every night with him until he was so exhausted he would just pass out around 2:oo in the mornings. When he finally did pass out his breathing was so shallow that I would put my hand on his chest just to see if he was still breathing. He could not go back to school, nor concentrate on anything. I have searched high and low for someone who can relate to this horrendous tic. My son told me he cannot believe he has to go through life trying to breathe. I hope you are still out there and see my post I would so like to hear from you and if any progress has taken place for your child. So, sorry that you also have to suffer like me to watch your child not be able to breathe without constant disruption is so hard!
