Anyone have experience staging an intervention?

It’s a long story and I’m tired and it’s late. But basically, this family “vacation” has, once again, turned into pure hell.

I’ve spent the past hour+ on the phone with a hotline to help me figure out what to do and he had some very helpful advice. I need to get my mother into rehab… like, tomorrow. We may never all be together as a family again (we’re visiting her father, and we haven’t all been together in 8 years at least). I can’t wait for someone to send me a professional. I need to try to get the family to talk to her and get her into treatment ASAP. We all head back home (I’m 3,000 miles away from her and the rest of the family) this weekend so I’m really short on time.

Today was a disaster. Just like the past 24 years have been, just like every vacation has been. I can’t let my little sister suffer through this anymore; I can’t take it anymore.

I know this isn’t very detailed but if there’s any advice you can share before morning it would be much appreciated. It’s been a rough night and I want to get this all organized first thing in the morning before she wakes up.

FYI, With the help of this professional at the hotline, I have found a place that seems like it would be very fitting for her… I need to discuss funds with my grandfather before I can go ahead and arrange anything. We are also waiting to hear back from the insurance company. The last time I approached my grandpa, he basically told me I was lying and cut me off because I wouldn’t support her. We had a moment tonight and I hope that he finally realizes what is going on. This is my last attempt. I don’t know what else to do. It’s exhausting and so painful.

I just need some guidance. :/
