I've been to Al-Anon meetings in the past and I really liked them. I am very introverted, too. I rarely ever said anything. I sat through the meetings with tears just flowing down my cheeks, just hearing other peoples stories, listening to some of the readings and just being part of a group of others who are hurt. Mine was related to alcohol--my fiance at the time. I was never pushed to participate, I could if I wanted, didn't have to if I didn't want. I will say it's all about finding one that feels good to you. I went to the same one for some time and one day at work was really really struggling and felt like I needed to go to a meeting so I went to one on my lunch break that was close by and I just didn't feel "it" there, so know that there are several in almost all locations. Good luck to you!
