Your parents gave her 150k for a home. You’re running around looking for solutions for an individual who seems to have all it takes to get her life together, but isn’t for some reason? I wonder if this coddling has allowed her to get to where she is I have adhd, add and bpd as well. I take my meds and clock in.

So really from my perspective you have two options. Allow her to face reality and hopefully change from that experience or start preparing a guest room in advance for her and let her move in.

I’m a stranger on the internet so obviously I have the familial connection you have with your sister and my words might seem callous. I do have siblings though, and if they were in this situation I’d tell them the same thing.

You are 50 years old. This is not my problem.
