My personal experience as i digested, processed my diagnosis was that the overwhelming nature of it all and my personal emotional response made my sob worse (i think the effect of anxiety was not only a real physical effect but that that physical effect was maded much worse by my anxiety) once i saw medical tests that showed breathing was not as bad as i thought it was, then aftfer i have been able to manage My response.

That said, it was probably only becsuse of that initial anxiety exacerbated response That i got things going with treatment

reality is it is better to err on side of caution. Better safe thsn sorry, right?
