If you're looking for folks who will be supportive of you going back to the Kingdom Hall, this probably isn't the best place to do it.
If being with JW family is what you think it takes to keep you off drugs, well, that's a tough one. I just hope you don't ever need a life-saving blood transfusion if you go back. (Yes, life-saving blood transfusions do exist.)
It's your life and you have to decide how best to live it. (Of course the JWs won't tell you it's YOUR life. But it is.)
I sincerely wish you the best life possible.
