Firstly, congratulations Katie on remaining sober.
You seemed so excited last week when Sfgirl (sorry if I'm not acknowledging the right person) who offered the links to treatment and meetings. I know you have said that you have spoken to your therapist and you have gone to some non 12 step meetings and that is certainly a start in the right direction. But what I find unusual is that you never mention anything about this, or what you are struggling with so people on SR could help you with your recovery.
As a side note, I would agree with self seeking with respect to legal action against the treatment centre. Law suits can be time consuming, very expensive and emotionally and mentally draining. You might be throwing good money after bad.
