She says she knew as soon as she met me. I knew bit by bit. Perhaps the clearest knowing was the night before her daughter's birthday two years ago. I was her last session of the day. I was so distressed I set off the fire alarm and then tried to jump out of the window to escape from the awfulness of the situation (my behaviour was really out of my control before DBT). She could have been really really angry with me. I think she was a little bit, actually. But she put me in a taxi with her and took me home (to my house, not hers)- and I knew.
