i'm not a fan of mindfulness nor yoga (practice), and definitely not CBT, but I hope you try this T anyway and try to go in with an open mind. It seems you've really struggled with finding a T, and I hope you can maybe allow the fact that them on paper may not be what is in your ideal world, but they can still be "good enough."

I am really sorry you regretted all that huge life-changing stuff you did for your dad. That is truly awful.
