Planning for after the day.
Days that I know in advance are going to be tough, but that I'll probably get through by dissociating? It usually comes too late in the piece to do much meaningful about it, and I'm mostly okay with dissociating as a coping strategy. Because it works, for me.
But if I know that I'm at the point that I'm dissociating to cope, then it's time to put real energy into emptying out my stress cup. Because being dissociated is not a way to live. Not meaningfully.
So I plan downtime, and I plan out how I'm going to use that downtime most effectively.
That's not me saying, "Meh, dissociating, no biggie". It's just a different way to come at coping strategies. Sometimes when I'm that strung out, it's probably less distressing for me to get through the worst of it dissociated, and deal with getting myself right again when I have enough space to breathe (and be distressed, sad, depressed, anxious, etc) and actually bring myself back from the brink. Because if I have to get through something (like work), it's not great for me to suddenly ground and be flooded with emotion before I've made it through that day.
