If you think you have a year to live, honestly, is this how you want to spend it? Tied up in the red tape of a lawsuit against the last of the many rehabs that "failed" to get you sober?
All I'm saying is... 1.check out the statute of limitations. 2.Get yourself sober. 3. Once sober, go after them with your faculties intact... bc they ain't right now.
Your credibility will be nil in court. The rehab knows this. There's no way in he11 they'd just give you your money back. They'll tie you up in red tape for as long as possible (which is reeeeeeally long) and meanwhile you're helping them out by upping the odds of the lawsuit outliving YOU.
Get sober. Just do it. Think of the resources you're marshalling to sue the rehab and refocus them on getting well.
Or don't. I am a nurse on a psych unit. I've seen the alternative... it's turning yellow and losing your mind and crapping your pants from the medication they give you for clearing the ammonia from your blood. It's dying in the ugliest ways imaginable. NOBODY thinks they will wind up like that, really, but.. they do.
