Welcome, there is lots of support & information here for you.
One thing in your post really hit home & that was the delerium tremens.
I just remembered a moment with my alcoholic boyfriend where he had been drinking heavily alone, I was real worried as had been acting strange & when I saw him he seemed to have voices & all sorts going on in his head. I would never have guessed that was what it was as I knew so little about alcoholism.
He was on antidepressents & had stopped taking them so could've been this too.
SR is great & I have possibly just learnt something from you also.
Keep reading as much as you can.
