I know the feeling. I know you want to help her through her morass. I know that you want to give her a little shove in the right direction and maybe things will change.
I think you have to squash the urge to suggest ways she can "fix" herself. My opinion is now is the time to listen, be sympathetic, be supportive, and not make any suggestions about what she should or should not do. She may be making a hasty decision, an incorrect choice, but it's hers to make and you may be the only one in her life that she can lean on. Just be a friend for now without any stake in the decision. She needs to work through her issues and it would be in your best interest to be seen as a support.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
