I need to tell someone about the abuse my brother did to me.
I'm assuming you've never told anyone before this point, am I right? It's been weighing on you and now you're ready to open up?
I want to get rid of all my pain about this case... I want to forget everything
You may never be able to forget everything, but by talking about it you can come to terms with what happened. You are traumatized and need to process your feelings.
I want my brother to feel the same way that I felt... and I want him to know how forgiveness works.
I think you should speak up about it. I applaud your courage for saying something.
