When my Chrohn's flares I just want to be left alone. I don't need your advice on something you don't understand and can't comprehend, just let me do me. Work

When my Chrohn's flares I just want to be left alone. I don't need your advice on something you don't understand and can't comprehend, just let me do me. Work has no idea that I even have Chrohn's because it doesn't affect my job performance and I cover it well. Peoples perceptions of you change when they know you have a long term chronic condition and it isn't always a positive change - I don't think it's conscious but it does happen so to avoid it, I just don't tell people.
