New Circle is New and I'm Old

I've recently found myself with a new circle and am facing an interesting conundrum. Their ways of doing things are very different than the way I'm used too with my old circle (who I had to leave due to a very large move), and I feel very much like I don't fit. I enjoy celebrating the turning of the Wheel with them, but when I was specifically invited to join the postulancy program and go through initiation, I was flattered but utlimately refused. "You'll make a wonderful high priestess!" I was told, and they're almost 100% right, but I'm already a high priestess, just not in their circle. I've led plenty of rituals, written more, and been part of a dynamic duo (if you'll pardon the phrase) for years before the move. Noone has ever crowned me as such, there was never a formal ceremony, but that's how I feel when I move in the circle. I'm no novice initiate, not a Maiden anymore, but a Priestess. There's no circlet on my brow or braided belt around my waist, but when I speak, the confidence is there, the assurance that I am creating sacred space, the powers hear me and the other participants respect me. The new circle is somewhere I'll gladly devote time and energy, go to potlucks and celebrate, but I wont be leading. It's not my place. Kam and Tanya are a good team but they've got a long way to go together and I don't want to get in the way of that, even though Tanya I think was really hoping I would jump in and take her place.
