I don't know what I can add to the excellent advice everyone else has given. Were it me, I think I'd want to know that I'd spoken up when I had the opportunity. Of course I've not had your life experiences with therapy and so on, so I don't want to cheapen any of that.
As others have said, you can only say what you know, and though it's all valuable testimony that will help build a case, what are the chances you'll be called to the stand? Probably a silly question; but about fifteen years ago I was called to make a written statement in defence of a relative accused - falsely - of child abuse. Other than that statement, I was never called to testify. Of course, I wasn't as central to the case as you are, so ymmv.

At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
