I agree with bipolarbear, after even having a therapist tell me, that certain things are personal and do not have to be divulged, and if so, you can fight "discrimination".
You need to feel completely comfortable to divulge to anyone info. on illness or disorders of any type. In your heart you have to feel you are alright to teach, if yoou are under a doctor's care you need to be sure to keep current with that, helping to prevent any oncoming episodes, etc. I'm sure many teachers have or have had some disorder.
I had a professor in college who was bipolar, he evn inform his pupils he was and how he deals with it and meds. Even had a guest speaker come to class to inform people about this disorder, besides the growing population of those suffering with depression.
I wish you luck with this.
Sincerely,
DE
