Im so sorry Hope .. I know that feeling of helplessness .
I can tell you what happened with my husband . I thought for sure that treating the ptsd first was the way to go but I was wrong . He needed to detox and have some inpatient treatment so he could learn other coping skills so when they did start therapy on the ptsd and he was stressed he would be able to handle it without drinking . Its a long struggle and we went through several therapist before we found a place where he could do his iop and meet with different therapist one on one each week . one for alcoholism , one for depression , one for ptsd . Hes was very happy and confortable there . Its still an uphill battle . We are still struggling .
Sending lots of prayers your way , hoping you make it through the day .
If hes willing today , you can drive him right to the hospital and he can detox there .. good luck
