TL;DR *Should I send her a final message*? Should I tell her my side of the story? That I was not faultless. That I was able to see the flaws in my actions. That I forgave myself and stop wallowing in self pity and pulled myself out of my self made misery.
I just want her to know how thankful I was to having her as my friend, that her actions saved me from myself. I also wish that she could be able to forgive herself one day too, and that she is the only one that could save herself from herself - only then could she achieve true happiness. Even though we could no longer be friends.
