Meetings are difficult, I would suggest taking notes instead of knitting. I often volunteer to be the “scribe” and take the meeting minutes because it forces me to focus on what is being said and helps me to stay on track. You also need to have a meeting with your supervisor directly rather than your coworkers and talk to someone in HR about possible accommodations for your ADHD. Talking with your coworkers about an issue between you and your supervisor may not be the best course of action because it may get back to her or him. Also, you may want to take your emotions out of it when having a talk with your supervisor about how to improve the situation and iron out any misunderstandings. You may want to ask HR about how to approach your supervisor and the formal process for ADA accommodations.
