Well, this past weekend she tried to visit for New Year's. She lives a little ways away. She left at 2PM on Saturday and tried to call and give me updates. She explained that she has depersonalization disorder which makes it very dangerous for her to drive if she gets into that state.
She called a few times, tried to give updates, but ultimately only made it two-thirds of the way before she called her aunt (who lived nearby) to pick her up at around 11PM (it was getting cold and foggy). She tried again the next day and made it only a few miles before freezing again in a grocery store parking lot. Her sister picked her up and her friend drove her car back to her sister's house. She's been there since Sunday.
I asked if she wanted to meet for dinner with her sister (and her sister's daughter) last night. At first she said yes and that sh would talk to her sister, but when I didn't get a call back, I called at 7PM and she said she didn't want to go.
I haven't heard from her since.
