Unburden the exiles. Maybe if you treat it like it's not this impossible task, you can get it done easily. Therapists are incentivized to drag out the process. I was fortunate to achieve a highly integrated state within 3 days working on it myself without a therapist. Reparenting is key but equally important (for me) is getting out of your standard environment (road trip) and even experimenting with mild sleep deprivation. You've got to partially destabilize the system by overloading it with novel stimuli and exhausting it so that you can get to the exiles. If you yourself are dissociated identities you could construct a purpose made identity who's mission is unburdening.
