New&Sad--very sorry to hear about how you have been treated, it's very unChristian and unkind. Jesus & God love you and have already forgiven you a long time ago.
I was reinstated and then faded, but the JWs I used to know treat me like I am disfellowshipped and don't speak to me. My sister doesn't speak to me anymore either. So getting reinstated is not all it's cracked up to be, but you need to do what's best for you.
Drinking problems are pretty common in the JW religion, partly because of the stress people are under trying to please the elders, the congregation & the Watchtower Society, in other words--trying to please men and not God. You are brave and taking a big step to get a handle on your issues, YOU CAN DO IT! But only if you have a big enough support group that includes nonJWs. I suggest that even if you plan to get reinstated, that you join AA, maybe get some personal counseling, and do all you can to build friendships outside the Kingdom Hall by having hobbies or different interests or taking classes.
I wish you much luck and hope to hear more posting from you!
