I haven't been through quite that much change all at one time and certainly see how that would be scary, but your last question resonates with me.

Over the years, circumstances have arisen in my therapy and mental health that were incredibly frightening. It was like jumping off a high cliff and trusting the air-bag would be in the right place when I hit the bottom.
Decisions had to be made, sometimes pretty much out of my hands, and I had to trust that the people directing those decisions where going to be there to catch me if I fell.

I generally have no problem trusting people with most things, and maybe trust isn't the right word. Your use of the word "faith" may fit better. You can trust someone with all your heart and still not have the faith that even their care will be enough to get you through the circumstance. Sometimes we feel beyond what anyone can save us from, no matter how much we trust that they care.

Over and over though through the years, I've taken those leaps of faith and I'm still here. The hardest part is taking that first step. Things don't always go just the way we want, but I did trust those people to help me through the rough places. And they were there. And I came out better for it in the long run.

Changes are scary. Let us know how things progress.
