So to explain, it isn't that I have a hard time breathing, breathing becomes no longer automatic. If I don't think about breathing then I will stop breathing. It is only during an attack, and not often does it occur during an attack. I usually notice when my chest starts feeling tight and I get light headed very fast. It doesn't last very long- five minutes maximum. But it makes me very concerned, and I haven't seen anyone else say they had this symptom or anything similar. I would tell my doctor but I am still on a wait list to get one. Has anyone else experienced this or something similar?
