DM, is this a co-worker, or a supervisor of some type?
It appears quite obvious that he/she is trying to show off for
the “brass” by belittling you, or ordering you around while in
front of them. That they are somehow superior to you.
Completely unacceptable. If the individual is not approachable
(as in you don’t feel comfortable talking to them about it), then
would contact that persons supervisor, and explain the situation to them.
Be professional, and let them know the persons behavior is inappropriate,
and hopefully they will talk to the person about it.
IMO, your ADHD has nothing to do with this…your co-worker is just a schmuck.
