Hi again,
I remembered you when I read about this:

Hi,Mycoplasma pneumonia is atypical and notorious for it's slow long course,I would say if she is still experiencing symptoms then the infection isn't gone completely or she was misdiagnosed. If she has already taken a course of antibiotics and you have insurance,then I would suggest a Bronchoscopy,with Bronchoalveolar lavage. The psychological or "depressed" presumption is just doctor BS speak for "I don't understand this,and I only have 5 minutes out of my busy day to talk to and understand my patients symptomology". The coughing by this point is more than likely pretty painful,so I highly doubt she is doing it for attention or just to stay home from school. If anything your Pediatrician should offer a referral to a pulmonologist not a psychologist. Amen
