Prayers for you and her. She doesn't seem to be in a place in her life that she can be a friend to anyone. She needs to heal and recuperate, and if it is meant to be, she will contact you. I would say, take care of you, no reason you can't carry her close to your heart, but live your life and don't put it on hold for her.
All you can do is pray for her and her recovery. Al-Anon would be a good support place for you to go to.
