How long have you seen her? One bad session does not a whole attitude make. You had an unpleasant time it sounds like but she may not have, she may have found you "challenging"

I always try to put a good spin on my negative thoughts. If you were challenging, that would mean to me that you were "invigorating" and that's a wonderful thing to be "making one feel strong, healthy, and full of energy."

Keep up the good work! LOL
