Thanks so much for posting this.
I thought that the chance of a successful complaint in my case was unlikely so I had never gone so far as to contact the "board". And so never went through, or even thought about, a victim impact statement. But, yes, I think I might think about that for myself, as a way of itemizing maybe what was the effect and what is me.
I feel and may look and sound like a mess, too, but I did manage to get out of my house of 32 years, and got rid of most things myself. I made what some may consider a poor financial decision on my house, selling to a rehabber for a fixed price rather than finish clearing out and cleaning up myself and waiting for a traditional sale at who knows for sure what price and when. But I got myself out, rather than being forced out by time or one circumstance or another, as I have seen happen to a friend and another acquaintance. I'm "old" -- 72 -- and had been feeling some decline, as well as depression that therapy had not helped and maybe hindered, but was still able see the writing on the wall and to act, some way, before the advancing fire, flood, invading enemy army, whatever you want to call it. So I do feel some positivity and gratitude that I was still able to decide and to act at all. If I had been more "well", then those decisions and the actions before them might have been better -- but that wasn't the way it was, so. . .
You have done what you can. The statement and your work on it will stand no matter what the board decides. The more statements like yours that boards get, the more likely it is, I think, that they may become aware of the prevalence of negative effects that therapy and/or therapists can have on clients. That's to the good, no matter what, I think. I hope that you continue to find progress, and perhaps some peace.
