First off, you can't so don't try! If she is having break through behaviors (sounds like one incidence of impulse verses poor frustration tolerance meets "no") then make an appointment with her psychiatrist and have them evaluate her status. It is common for adolesents with ADHD and a mood disorder to have new medication needs during this time, they are changing fast, and will need very close medical support and supervision. If your psychiatrist is not able to see her as often, or as quickly as she needs, have a discussion with them about her need to see them quickly, and if they cannot accomodate that, find one who can. It is VERY common for there to be vast changes in needs at this age, so instead of looking for a new diagnosis, look to the one that she has, it can totally explain this behavior, and needs more attention from her psychatrist.
Good luck to you, I feel your pain.
