hi shangrala
i have been in a similar situation with my family
the only thing yuou can really do is just be there for her.
when and if she is ready she will ask for help, but there is noting you cna do to get her to that stage.
so just be there for her ready.
i am sure she will one day, but you will never know when that is. it might just happen. it is really hard but that is the best thing you can do for her right now.
i think some kind of denial comes with depression too.
hope you are looking after you though.
