The thing about bullies and narcissists and drama queens is that no matter how much therapy they get, you can't make them "care". The only reality that matters is THEIR OWN. And they DO like to create their own reality and have no problem lying and pretending they are more important than they really are. If you hand them information all they do is use it to empower themselves and put down any person they consider a threat to their gaining all the attention and praise and power and control or "feed". They are basically "users". And they are superficial, they don't really have the ability to be "genuine". You are only wonderful as long as you service THEIR NEEDS and service THEIR ego and follow THEIR rules and you are there to be used and THAT'S ALL. It's always all about THEIR security, not yours. If you dare to object to that YOU are always going to be the crazy one. That's why NO letter or SPEECH will have any affect on them other than making them angry where they go on their smear campaign. They are already masters at DEFLECTION.
You will not get anything from them, ofcourse they are in need of using for a feed. Yet, with what you did write, as seesaw so nicely stated, you will get the genuine sympathy from others who themselves experienced an individual like you are describing.
