You are not a monster. It sounds like you were trying to protect someone not harm them. Unfortunately while she's battling this she may not see it that way. Stop hacking into her email, you will drive yourself mad. Maybe just reach out to her and let her know you're there if she ever needs to talk, but then leave it at that. I'm sorry she's dealing with that and hope things work out well for her.

well your first mistake was getting into her email... as you know. If you were that concerned you should have tracked her down in person.
At this point, you probably just need to move on and leave her alone. Yes she might hurt herself, but that isn't your fault it is her choice. That said, she probably isn't going to hurt herself... but whatever happens, she does not want your help, that is clear. So i would let it go.
I am sorry it has happened to her.
