Q: I have adult attention-deficit disorder. After a recent mishap at work, I brought this to my boss's attention.
She said she knew nothing about ADD but was glad that I told her. Since then, I have noticed that she treats me differently.
My co-workers talk about me behind my back and think that I am just plain dumb. That is so far from the truth.
What advice do you have for someone in this situation?

A: People with "hidden" disabilities often face an ironic choice.
If they conceal their diagnoses, others may not understand the challenges they face.
But if they reveal their problems, people may regard them differently.
By telling your boss that your mistakes were caused by a permanent impairment, you have changed her view of your ability to do the job. To alleviate her concerns, explain how you will prevent similar errors in the future.
Before you get too attached to this diagnostic label, however, be sure that you have been examined by a qualified professional. The term "adult ADD" is often carelessly applied to anyone with a short attention span.
If you have been officially diagnosed, you may be entitled to legal protections under the Americans With Disabilities Act. Your human resources manager can provide information about required documentation.
To silence your colleagues, let your work speak for itself. If you are consistently careful, thorough and accurate, their opinions will change.
But if you are unable to perform this job successfully, consider finding a position that's a better match for your skills.
