Clarify the agreement that existed
Identify the promise, policy, schedule, ownership, or shared understanding that applies before assigning blame. For a message about how to support someone with an autoimmune disease, use this factual base: use the person's description, note the access barrier or practical need, and avoid guessing about severity.
Resolve the next dependency
State what is complete, what remains disputed, and which action would move the situation forward. Ask which accommodation or form of help is useful and follow through without making it a favor. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Document without threatening
Do not demand medical proof in a personal relationship, offer cures, or frame disability as inspiration. Use qualified clinical or emergency care for urgent health concerns and the proper rights process for denied accommodations. Keep a factual record and describe only remedies you are entitled and prepared to use.
