Peaches, as part of learning to do that (tell your t as soon as you are aware of it) you can just do the best you can as see where it takes you. It doesn't matter if the cascade has already started before you become aware and present enough to say something. By letting t know at that first awareness of it it will still be sooner than you have let her know before. It's okay to not be perfect at it yet.
