I hear you talking about your fear of any new t not being right for you and I know what you mean. I am starting out with a new t and I am terrified she won't be the right fit for me too.
But while the fear is relevant and appropriate in the situation the possibility of finding a GREAT t is also relevant and appropriate. You could find someone awesome. You don't have to settle for something that doesn't quite work for fear of getting something worse, because you can always keep looking for the T that feels right.
If you stick with a t that doesn't quite fit you could potentially be missing out (right now!) on a t that fits you perfectly.
