Glad to hear she'll get the legal help she needs, that situation is awful.
Great job being there for her, a lot of people don't get support when they get abused. I'm sure it means a lot to your aunt, I hope she feels better soon. If she feels lonely at all after this, getting a pet could help, too. Animals can provide a lot of companionship and healing at times like this.
Hope you take it easy, too. No one can tell you the right way to deal with crazy shit like this, whatever makes you and your family feel better, go for it.
