Sounds like you have a right to be hopping mad at this guy. Maybe he thinks if he arranges this service you won't have the heart to get him away from your dad? Is there legal recourse you can take beyond the POA?
I don't think there is a single thing wrong with your purchase. Sometimes we need to cast off old "things" that remind us of the past, and get fresh new ones. New bedding is a wonderful gift to yourself. I hope it helps you sleep.
I spent way too much money in the beginning. I kept telling myself it was just money that I would have spent on booze but it got a bit out of control for a while there, LOL. After some time working on myself and getting at the underlying reasons I drank, the spending leveled off, because I got better at finding ways to feel good that didn't have anything to do with alcohol, food, or spending. Like Fearless said, we are works in progress.
