Dang, I just lost my whole comment. I hate my new netbook. That's partly why I don't come here as often anymore.
To recap, briefly:
I'm sorry it's so hard. I can relate to feeling obliged to put up a happy front at home, despite the supportive partner. It seems too hard, or unfair, to burden day-to-day functioning with the deep struggles and depression that claw at us. I'm curious: why the lack of therapy right now? Can you throw an occasional email to your T for support? It's good your insiders are communicating, but maybe there's a way to slow it down, for everyone's sake, maybe agree to set aside a certain amount of time every day or weekend or whenever, depending upon your schedule, for a certain number of them to write, draw, tell their stories. Our insiders signed up for time at therapy, which, much to my surprise, worked. Maybe they would agree to that? It may seem as if nothing would slow down the barrage of insiders and memories, but it's worth dialoguing and seeing what may work, esp. if insiders see that it's to their advantage, as well, and that you'll honor the agreement with them, whatever it is (so make it realistic!).
We also haven't told others about our DID, except our partner and T (and a couple of DID friends who were there when I was initially diagnosed but who are not a part of my life anymore). It's really a drain to keep the struggles hidden behind a functional front. We have to remind ourselves that we are dealing with a lot, and so the fatigue and myriad of stressful emotions make sense.
I wish we had more suggestions. Just one more: be gentle with yourselves, find ways to self-nurture. You are doing good, hard work. You deserve moments of joy and relief, too. Even little gestures of comfort can help soothe. For instance, we sleep better with certain toys that the kids associate with comfort. Occasionally we feel like blowing them off, then we have trouble sleeping until we go get the items. It may not alleviate all the anxiety, etc., nor does it reduce nightmares. But it does provide enough soothing to take the edge of the kids' panic so we can settle down and fall asleep most nights.
Take care. And keep writing here if you can.--orek
