Making decisions can be one of the most draining tasks, especially if they are emotional decisions. I look around my office, and see so many unhappy people and hours wasted because the decision was not made, or was made by someone who then felt uncertain. And your situation is so much more complicated than whether a report should be bound or not (yes, really, yesterday, we must have had 8 people spending on average an hour discussing the pros and cons )
My sense is that as D turns into an 18 year old lady, she will be less dependent on her mum doing things to make her happy. She may also need to see the example of her mum living an authentic and happy life. You've done such a great job thus far, I'm sure you will prevail. Even if some days are harder than others.
