She no longer exists to me. - Comments

If your friend is feeling this way I know you've said how you feel but think of how she must be feeling for her to even want to leave this earth, she needs you to be there for her, maybe she needs to know how upset the thought of her being gone made you feel it might need what she needs to hear so she knows how much she'd be missed

If this is how your friend is feeling, she needs people to be there for her, not to treat her as if she's already dead.
