Anyway. Long story short, I've been in therapy for quite a while--dabbled on this site a while back, too--and recently, I've managed to get into college! Whoo!

Unfortunately, that means a lot of changes and a new T for us. She doesn't know about any multiplicity aspects--just the "us" we show to everyone else. We've never gotten an official diagnosis, which makes bringing it up with a new T a bit of a rough topic. We haven't disappeared with lack of a diagnosis though, obviously, so a DX isn't top priority to us. Instead, we focus on living a multiple life as smoothly and happily as possible. (We unanimously agreed that integration is not an option--we rely on each others' companionship and being on our own would be positively terrifying. We like our arrangement.)
Anyway, new T! She's nice, open-minded, and I don't have to pay for her sessions thanks to the college's insurance. However, bringing up this with a new T is tough, and made even more so by the fact that we feel we've come a long way with our previous efforts--we coexist pretty well (although if things get rough, a bit of guidance might be required), but we don't need a lot of psychoanalization about why/how/what to do.
I've been seeing this T for a few months now, and there's quite a few things that screw this all up, one of which being a possible physical gender transition in the future (discussed between all headmates--we take our cooperation protocols very seriously). Also, some of our own have been running into difficulty with things like anxiety lately, which could go over like a ton of bricks if not dealt with appropriately, and is causing a fair bit of unease.
Guess I'm having telling-T-nerves. My first T ended up making all of us pretty uncomfortable--despite our desire to avoid integration and keep our focus on cooperation, all the focus in our sessions was on how everyone else was a "part of" and not a partner. So... tips on explaining that we're not looking to be cured or treated as fractured/separated-into-parts to be put back together, but looking to focus on living and getting support for those of us that need it? Or, you know, tips on relaxing about telling a new T...?
