I dont know that you can accelerate the changes that you make to yourself. It is a process and you need to have patience with yourself. It will take some time.
Part of it is doing the work. Talking to a counselor, reading self-help books, meditating, whatever it is that you need to do to work on yourself. If you arent doing the work then changes are not going to just happen spontaneously.
However, the other part of it is simply "fake it till you make it." Even if you aren't there yet, you can simply act like you are when you interact with your W. Obviously, you want to get to a point where it is real, but in the meantime the W doesnt need to know that. Read Sandis rules, read her comments on your thread and use them as your guide when in doubt. If you know you are going to interact with her be prepared. Be positive and friendly but know what are safe topics and what to stay away from.
Good luck
