Gee, that's just awful, BP. Awful for your friend and awful for you. Such a shame her Mom didn't haven't any faith in her.
Thanks for sharing your experience, even tho it was so tough for you. It's a lesson for us all to reach out whenever we can, but to know that ultimately it isn't something we have control over. It wasn't up to you to save her from herself.
It was
HER choice, not yours, so no beating yourself up. Like Alffe said, we just can't give someone the will to live.
Many hugs to you, BP. You are loved
