Vocal Cord issues and Asthma

I have been a long term asthma sufferer. Lately my nebulizer and rescue inhaler will not get rid of the tightness in my throat/chest. I get episodes mostly at night, but it could flare up at any time.
My allergist (new to the practice and wonderful) suggested that since the steroids did not help, and the fact that my anxiety over husband’s health issues and the death of my sister complicated the issue. I am on Prozac now and feel better mentally but my allergist did a pulmonary function test and showed me that my vocal cords were strained. So off to an ENT doctor, and now I am waiting for their speech therapy doctor’s appointment.

I went on YouTube and have Been doing the breathing exercises and they are helping somewhat, but now I have either a cold or allergies and asthma flare up is bad.

Any suggestions? Anyone have a vocal cords issue with their asthma, I am at wits end and losing much sleep.
