Good luck Want.
No advice really except that although AA does have cultish aspects I would imagine in the SF area agnostic and other 'flavours' are available. Here in the UK religion is not a major part of many - possibly the majority of groups and in many the 'spiritual' aspects are played down - given we are pretty secular as a nation.
It is early days for me, but I am learning something else from AA. To keep it simple. Some of their slogans are based on the experience of millions and some of them really mean a lot more than they might appear to on the surface. But you already know that.
All the best. You can do it!
