All Al-Anon meetings are a little different. Some focus on steps, some on topics etc.
The reason I say this is that they all have a little different feel so sometimes it takes awhile to find one that fits.
Most of us have gone to Al-Anon meetings and found that we are not alone in our experiences of living with someone with an alcohol problem. However many of us have found bringing someone with us can get us through the door. I am not sure what you mean about going alone? Do you mean bringing a friend or family member with you?
I did not say much at first when I went to the meetings, but I still learned a lot. I am a reader and read all the books Al-Anon had to offer which really helped me.
Al-Anon has been a huge part of my recovery and healing.
