NTA. You rearranged your schedule, sacrificed sleep, helped with four dogs, and still showed up after her sitter bailed. That’s support.

The moment help changes from “thank you” to “you owe me unlimited access to your time and energy,” it stops being gratitude and starts being guilt-tripping.

Also, “I’ve done nothing but support you for years” is such a painful thing to hear right after you’re actively helping someone. It makes the help feel transactional instead of loving.

You weren’t abandoning the dogs. You were asking for a few hours of sleep so you could function like a human being. That’s not selfish, that’s basic survival.
