PTSD and addiction, particularly opiates

I have a history of longterm physical, emotional and childhood sexual abuse lasting approx 14 yrs.  There have been many other life stressors.  I've made five suicide attempts, starting at age 16.  I'm currently 38 yrs old.  I have been diagnosed with bipolar 2 disorder, PTSD, and borderline personality disorder in the past.  I also have a diagnosis of chemical dependency.

Every study I've read (and I've researched this an incredible amount in the last week) has indicated very poor recovery rates for addicts who are not treated concurrently for their PTSD as for their addiction.  However, of course, "the issue is that I just need to stop using drugs".  I've been clean for ten days now, but if the PTSD isn't resolved or at least dealt with, I WILL use again.  This last event took me from reasonably stable to suicidal within a matter of weeks.  There's been some studies into using naltrexone during PTSD treatment to prevent that endorphin release and enabling the patient to remain "in the emotions" during therapy, but I've not been able to find a therapist that seems to have even heard of that.

Just looking for opinions.
