What's the Reason Behind My Fast Breathing?

Question

I noticed that I am breathing very faster than normal level. I know I am going to face another asthma attack soon. I cannot go up a flight of stairs or walk for so long. I did not have enough sleep last night. Will it be a reason for fat breathing? I forgot to take Advair last night and I don't know forgetting once will make this much problem. I slept in a dusty room last night. I know it is stupidity and I’m going to clean it soon. As you know, I am on Advair for a long time. It has some bad effects on me. I am using a black labeled one. I feel cough and congestion some time. It also makes me hyper but I can adjust with all problems for recovering from asthma. Do you ever experience fast breathing? I can even feel it when I am sleeping. I don't know whether to go to the doctor or not. Any way I decided to stop Advair for some days.
