It doesn’t sound like it worked out. Hopefully your new clients are a better fit.

Honestly since these people are in need of a care giver and have probably pretty high level of ASD it’s probably expected that there would be challenges. If there was no challenges and they had no difficulties, they’d not need a caregiver. I’d try not to think of your clients as “dumb” or “brats”. It’s subjective. And not very fair since you made a choice to work with vulnerable population

Good luck with new clients
