So for her complaint "Continuously calling her family members to tell them she is ill", you said that you only texted her sister once, but above you say that you called her other relative twice AND sent a text about her mental condition. I guess that's where that complaint came from.
You can't fix whatever mental issues she has, nor can you own them -- she needs to do that. Continuing to pursue that with her and around her only underscores that you do not accept her as she is, that you think she needs to be fixed, and that you think you can fix her. Back off on that.
It is perfectly appropriate to care about the ones we love and want to help them, that's a normal and admirable thing to do -- you just can't do it now.
