I Am A 55 Year Old Female - I Work

I am a 55 year old female - I work in an office in a City Hospital. For the last month or so - I have had problems with my digestive system. I go about 5 times a day (never have before) and I drink TONS of water and have had little to no appetite and have a low grade fever & a horrible cough that just will NOT seem to go away - despite being put on antibiotics for Bronchitis (Biaxin) - I have not been on any meds but have tried to replace Coffee with Camomille Tea and have tried to say NO when I mean NO instead of "people pleasing" and saying YES when what I mean is NO...I am under stress at work but at my age and with my pension, I have no choice but to weight it out...I would appreciate any insight into what you think might help. I already take Probiotiocs and exercicse 3x a week.

THANK YOU in advance
