my instinct reading what you wrote is that you need so badly to get this information out, that you need your story told, to have someone tell you "what you went through was terrible and it shouldn't have happened"

I might be wrong....but that's what I got out of your words. I want to give you a hug right now, I am so sorry what was done to you.

You don't have to share details right away if you aren't ready. You don't even need to discuss the journal entry if you're not ready. But maybe the act of even giving her the note is a valuable part of the healing process for you...there is no right or wrong here. Even if you want to give it to her sealed, and have her read it later as another "step"

Another option is to re-write the journal entry into a letter for her, with the basics of the initial journal entry, but addressed to her perhaps will make you be able to share but also retain some of the "control" in the situation.

Whatever you decide, let us know how things go. Best of luck to you and I'm sorry you hurt so much
