Breathing difficulties

Been dealing with a bout of shortness of breathe on and off. Sometime I can't take a full breathe. I noticed that in the morning I am okay it's just later in the afternoon, I get this way. And especially when my son is becoming a teenager and don't do what is asked of him drives me up the wall. Day in and day out. My sleep has gotten better knock on wood but am still on klonopin. I ask my psychiatrist and he said it's not the klonopin that is causing my shortness of breathe but my anxiety issue still looms. Who's right? Sigh!!! I do have to add that there are days that feels norm but not by much.
