I wish I could have wished her peace from whatever she was suffering from but I found this thread a little too late. I'm happy that there was a person who supported her through all of this which must've be comforting. Also, most of the comments were positive and supportive of her choice to leave this Earth. However, I was feeling upset about that one individual who kept on trying to "save" her.
As many already posted, it's her decision and she was sure this was the right action to take. I don't know exactly what made her want to CTB, but I understand it was health reasons (but I may be wrong). That one person kept on saying "I've been there... Blah blah blah". No you have not been there because you have no clue at to what she had been through in the past or even around this time before she CTB. She clearly stated she didn't want anyone to post things that would try and deter her from going through her plan. Yet, this individual kept doing what she asked everyone not to do. You should always respect someone's wishes and try to show some compassion for the individual. I understand that "creeper" may have had good intentions because seeing/listening/reading that someone is going to take their life is not easy. It's human nature to want to provide support and "save" others in whatever way possible. But, as I mentioned above, how do you know what she was going through exactly? Do you know anything about her life growing up and into adulthood? Do you know about her job situation or finances? Do you know anything about her personal life? Do you know about her physical health? Yes. You can offer to speak/text to offer support and encouragement, but if they are firm in their decision, then that's something you must respect. Let's say she was suffering from a severe, progressive, incurable and painful medical illness. What would you be able to do for her? You can't take the disease or pain away can you? The OP clearly said not to try and dissuade her because her mind was made up, but you couldn't comprehend that.
I really wish the OP found her peace in the end without much struggle or discomfort.
RIP
