Stuck

I'm emotionally exhausted right now.

Susan and Lisa both agree that unless I confront and/or forgive them and move on that I can't fully recover. And since I'm afraid to confront them, him especially, I'm afraid I'll never be fully over it.
She said- what if you write letters to never send-
But you see, I've done that. I've done that many times. It doesn't work. It's not enough.

He said- maybe it'll be easier to do when I've moved out. That it might be awkward to do now, while I'm still in the house. But then that means I have to wait a year and a half.

I can't stand this for another year and a half.

But why can't I just move on?
Why can't I leave it behind and stop letting them ruin me?
