I know what it's like to not be in control and just pull. I used to not even notice that I was doing it. It's taken me many years and a LONG time to even get to where I am today and finally have SOME control over something I've never been able to. It's a hard process BUT it CAN be done. So, if I were told that, I'd be very offensive as well. You're not in the wrong here. It's like telling a person with Tourette syndrome/GTS "I know why you have tics now!"
