While I recognize your initial post was a while back, here's my input. I got calendars on my wall and plan things to do that they will like weekly....it is a distraction, a real mood changer, and attention given to those parts and it prevents dissociation or staying in bed wallowing. So for example, my white board on Monday may have the house cleaner coming.....and we all work together for a clean environment and afterwards a reward.....go to the pool and do water aerobics (the pool is good as is the bath tub), another day I work on teaching materials and for those parts that cooperate....we watch a cool movie in the evening, listen to music we like, or take a walk.....exercising usually helps I've noticed....another day I do clay sculpting or painting.....another day....I take us all for a walk in the park....and so forth. So, I plan distractions that work for the majority and that seems to help keep me on even keel and when my T cancels or some other person cancels.....we suck it up and do something else that is fun/distracting. That really helps "prevent" my funky crappy moods and is emotionally stabilizing. It keeps my end-it-all part busy having fun rather than starting shit thoughts in my head.
A second thing that I do is have group meetings in my head, and use emotionally sensitive language...or more carefully crafted language geared down to kid self-talk.... when there is a problem or a situation that needs attention. Everything has a price (pos. or neg.) and most things can be turned around....for a price (reward, bribe, etc.)-call it what you want but I can bribe my parts to clean the house.....on task behavior=reward. I've worked with my parts to get them to believe I have their best interest at heart....they can trust me to keep them safe. So, diversion.....getting out to fun things....light shows, Xmas tree light ups, New Years fireworks (I know they don't work for everyone), free musical things in the community, exercising regularly-getting out from under those comfy covers, doing my hobbies.....it's not just one thing....it is things all of me enjoys.....taking turns hasn't been a problem much. Hope you are feeling better. Good Luck.
