I STILL CAN'T BREATHE HELP!

I recently found out I have asthma. I was breathing at 54% capacity. I have been complaining of being "breath hungry" my whole life. It is in my medical records.
I started less than a month ago taking welbutrin, singulair and advair (i think) I still feel starved for breath almost constantly.

WILL I GET BETTER EVENTUALLY? Are there stronger MEDS to take?

I am also on anti-CANDIDA TREATMENT (I don't know if candida contributes to asthma)
I also have fibromayalgia. Shallow breathing is a common problem with fibro.
HOW ABOUT TAKING HYDROXYGEN?
If anyone can help me I would appreciate it.
