As I have said on these forums before I am a teacher. I am an alcoholic and I am also on SSRIs for depression. Despite mental illness being supposedly ok to talk about now I will not let on that I take these meds and I would never let on to folk at work that I am an alkie (there is only one trusted individual who I have told).
When people retire or leave the school they always do a speech in the evening at a social gathering. When I retire I will stand up and 'out' myself on both counts and let people decide then if my work suffered in any way over the years.
