One Sibling Does Everything and Resents the Others

Before anything else: was this division always the pattern, or is it new since the diagnosis? Most of the time, it's old. Whoever lived closest, or was the most organized, or simply answered the phone first, became "the one who handles things" years before any of this started, and nobody sat down and agreed to it. The role calcified by default, and now it's load-bearing.

A few things usually keep it that way. Asking for help can feel like admitting you can't manage, especially if being capable is part of how you see yourself. Past attempts to ask sometimes got a lukewarm response once, and that one experience quietly became the reason you stopped trying again. And it's worth being honest that the imbalance isn't always one-sided: sometimes the sibling doing everything also has a hard time actually letting a task go, correcting how a sibling did it, or redoing it after the fact, which teaches everyone else that helping isn't worth the effort. None of that makes the resentment less real. It does mean part of the fix is available to you directly, not only from them.

Make one small ask before you make the case for a full renegotiation, since a full renegotiation is a much harder yes.

1. Pick one narrow, recurring task and ask for it directly this week, rather than raising the whole imbalance at once.
2. Write down the actual task list and share it. Siblings on the outside often underestimate scope rather than refuse it, and a visible list does some of the asking for you.
3. Practice letting one lower-stakes task go imperfectly done. What gets delegated and left alone is what actually gets picked up again next time.

Note whether particular requests get declined, or whether they were never actually asked, just assumed and resented when they didn't happen on their own. Also note your own reluctance to hand something off. Both patterns point to different fixes.

You are allowed to be furious about the imbalance without needing every sibling to feel exactly as guilty as you'd like, and you're allowed to keep doing this work even while you're angry about doing it alone.

This is what the tracking is for. A specific, dated pattern of asks and responses turns a family grievance into something a mediator, a lawyer, or your own doctor can actually work with.
