This sounds really uncomfortable at best and I’m so sorry you’re dealing with it. My experience is that I question my gut instinct, try to find ways to blame myself, and fear setting boundaries with people as I don’t want to upset or aggravate them. I’m not sure if you relate. From what you described, I don’t think I would use the term ‘bullying’ but I would definitely label you coworkerker’s behavior as disrespectful. I don’t suggest telling your boss about your ADD, but this is from my own experience. How would like to envision this situation working out?
