I'm not embarrassed by my epilepsy so telling people doesn't bother me. If it's someone I know I will spend time around I'd rather them know than not know that way they can respond accordingly

I feel like if my speech or question will affect them.directly yes.

If I'm going to be working with them or going to be around them for hours at a time for some reason, yes.

I don't let anyone know unless I am close to them, cause if others don't know they will treat you more normal.

Depends on how often seizures occur for each. My frequent partials in public simply want all to know I'm okay after. Why hide or be embarrassed by any health issue? Let others see the bright side of epilepsy. Seizure come & go able to walk, talk & think normally. Relax all minds including yours.
