She sounds really awful! Seems like she's totally misinterpreted Tolle's teachings and using it all as an excuse to mistreat other people.
I can't deal with flaky, indecisive people like that. I had a similar experience about 8 years ago with the new owner of a local art gallery. She found some of my local photos online, and wanted to display them in her gallery. That led to me offering to create a website for her shop. I spent time creating an example website, and then took the time to take great photos insider her shop using my DSLR. Then she changed her mind and said she was just going to use a Facebook page and her own photos.
I think this highlights the need to get things agreed in writing in advance, and for large projects to possibly even get half the money up front.
