Anyone dealt with a nonstop barking cough?

Hi,
I'm 18 and a year ago I got pneumonia. Ever since then I have been left with a chronic barking cough that is deep and painful and almost impossible to ignore. Every time I get a cold it gets worse. I've had CT scans, asthma tests, x rays, allergy tests, blood tests, a scope to check for VCD, have gone through speech therapy, and pretty much anything else i could think of. I can't find anything out of the norm. I've done a neurology test, where the monitor brain waves, and that was normal too. I've seen a psychiatrist also. The speech therapy got rid of my shortness of breath but did just about nothing for the cough. The cough disappears with sleep, except for when I get a cold I may wake up once or twice to cough. I used to be an athlete who trained all the time but stopped playing my sport since I got sick. I don't know who i can talk to about this because I have tried to live with it but it keeps dragging me down. I haven't been able to find anyone who understands how I feel and i feel so alone with this. I don't know what other doctors to see and nothing alleviates it besides breathing in a lot of Vicks. I was supposed to go to college but ended up deferring because I could not get my health problems in order. I was supposed to have tmj surgery to stop my jaw pain but then I got sick and couldn't. I'm really desperate to find someone who has gone through this and understands because i can't take it anymore.
