Yes, I suppose it´s worth a try. Too much of self destruction, relapses, a massive soul destruction in general. Not to mention manipulative behaviors. It must be really tough to get it all out.
I remember when I first started going to NA meetings, over a decade ago... I thought that I would have to publically confess in front of a room. I also wanted to find any and all excuses to not be there.
Now, I realize I choose what to share and how to share it. Last night I shared that I had done some "vile shit" (long story, I was trying to relate to an uncle of mine who has done some terrible things in his addiction) in my addiction. I then said that while I haven't done what he has done, anything is possible in active addiction.
Now obviously, things like the 4th and 5th step are more specific, but that is only shared with one other person and by the time I got there I was more then ready to do so.
I'd suggest just attending. Try a few different meetings. If you don't like NA try CA/AA and/or SMART. There is also a newer group called Herion Anonymous which I have never been too. Personally, I like how NA includes all substances and focuses on addiction rather then a specific drug. Shit, there are behaviors that I can indulge in that can be just as bad if I want them to be.
I've found that it's about 50/50 between AA meetings that allow discussion of addicition to other drugs or just alcoholism. It's can be a tricky thing and you can have a room turn on you fast. The best way to determine if a room is 'addict friendly' is to sit and listen for a few meetings.
Yeah, it really depends on the area. Young People AA meetings tend to allow discussion of drugs, but those aren't always the healthiest meetings. Also, there are sub "movements" within AA that are trying to bring AA back "to its roots". For them, this means reading only the first 164 pages of the Big Book (which is what the first edition was), identifying as an alcoholic only, talking about alcoholism only etc etc. I have been to one of those meetings once and it was very much not for me. But like I said earlier, I don't personally attend any other 12 step group besides NA.
