Hi EM, sorry that this caused you so much distress. Big trigger, huh? Teacher T was definitely wrong. This is getting worked out though and now you have all the info. Everything is out in the open. You are angry and have every right to your anger. Now you can go to therapy and work this out.
The bright side of this (sorry, I'm an extreme optimist

) is that a trigger has been pulled up for you and now you are problem solving it and working on being able to handle your anger. This is worth about 6 months of therapy. You will be stronger because of this!
