she has her own path to take, and her friends at church probably do suspect it, but will probably pray for her.

She has to find the strength herself and rescue herself, and it sounds like you feel the need to rescue her, but sometimes, it's better to stand back and get her to do that for herself, it's difficult but more empowering. So don't feel guilty for taking a back seat now in order to look after yourself. Don't punish yourself for this.
