That would have really hurt me as well. I mean really. If my T said something like that I would totally shut down, why bother saying anything else? I'm kind of mad at your T that she said that! I almost want to tell you to fire her, and my gut feeling is you should. I personally need my T to believe me. If they cant believe me because "they weren't there and are only hearing one side of things" then they better bullsh*t really good, because I wouldn't be able to talk about my story to someone that could think so lowly of me.

I would definitely NOT give her the letter. Even though you don't mean to threaten her now, there is just too great a likelihood it will be misinterpreted. She could have you put in a mental hospital with the note as her proof. Also, I'm shady about her in general given that comment she made.

I would talk to her about your anger specifically about the comment she made. If you want to mention the threat I would be vague about it.
