I strongly think you should find another T! He forgot your NAME? That's inexcusable. Forgot your appointment? Also inexcusable. The things he said to you about having a bad life, and not living in the past may be all right in some kinds of therapy, but not said in a confrontational way.

He sounds very toxic and mean! Maybe he has emotional problems of his own, and has some memory loss, but it sounds like too much all in one person who is supposed to treat you with compassion so you can trust him.

I'm glad you walked out. I'm sure you'll be able to find a better T.
