I've had many Ts, and more than one who were "right" at the time.

Ts that I have seen and stayed with: 3
The first one was great, but I only saw her for a couple months. I had to stop seeing her when I graduated high school. The second was awesome and so kind and caring (very mother-like) but I could only see for one year while I lived in college dorms. When I moved out to my own place, she referred me to my last T, who has seriously saved my life many times. She's absolutely incredible. However, I can only see her while I'm at college, so we have our last session in two weeks.

Ts that I saw for more than 5 sessions but weren't the right one: 4
One decided I was cured after 6 sessions, two were just really bad, and one who was really good, but just not what I needed at the time.

Ts that I saw for less than 5 sessions: 6
Most of them were for reasons outside of my control, since I usually use 5 sessions as my judgement mark. Two of them left their jobs for something else, two stopped calling me back, one decided she just didn't have the room for new patients, and one I just knew wouldn't work.
