Chosen care
The method is short, and it starts with a decision you've been avoiding because making it feels like setting a limit on love. It isn't. It's setting a limit on penance.
Decide the amount. Sit down, on your own first and then with your partner if you have one, and write what you can give freely. Not what a good daughter would give. Not what you gave last month at the cost of everything else. What you could give every week for two years without resenting it. For most people that's a specific visit on a specific day with a start and an end, a specific number of calls, and a short list of jobs that are yours. Sunday, two till four. Wednesday evening on the phone. The prescriptions and the hospital letters. Write it down, because a number in your head drifts upward under guilt and a number on paper doesn't.
Say it. To her, warmly, as a fact. I'll be over Sundays from two till four, and I'll ring on Wednesdays. That's what a frightened person can hold, chapter 16. Say it to your siblings too, chapter 21, and to your partner, who's been waiting to hear that there's an amount.
Give it whole. When you're there, be there. No cooker clock, because four o'clock is already decided and doesn't need watching. No calculation about when to leave, because that's settled. If the afternoon is good, it's good. If she's difficult, it's two hours, and two hours has an end. At four, the doorstep, chapter 7. I'm off now, Mum, see you Wednesday on the phone. Then go.
Stop paying twice. This is the part that takes practice. When the should arrives on Thursday, and it will, you answer it with the amount. I'm giving Sunday and Wednesday, and that's decided, and Thursday is mine. The guilt will say it isn't enough. You've already answered that in chapters 5 and 18. It was never going to say anything else, and the amount is not up for renegotiation by a feeling.
Then watch what happens over a month. Most people who do this, and this is my expectation and not a finding, give about the same amount they were giving before, or slightly less, and find that the visits are better, that she's calmer, that the drive home has no second guilt in it, and that Thursday is a day again. The amount can be raised later, on purpose, if you find you want to. Raised, not drifted. That's the whole difference.
