I totally agree with Cat & Anvil, you are not her last chance and certainly not her best chance.
You are caught up in the emotions of the circumstance. This is not your battle to fight, it is hers.
I admire you for wanting to help, but, jumping in at this point will be of no help whatsoever.
Try and relax, think everything through, she knows what she needs to do, it is totally up to her.
