My opinion is:
You put so much of your thoughts and feelings into your post would it do any harm to go to a meeting? You can't knock something 'till you tried it.... I feel for so many reasons you should try a few meetings. You may like it, and if you don't then you have something to use as an example of why you don't like it then preconceived thoughts... oh PS, you don't have to say one word at these meetings, you can just listen and if for some reason should someone ask you to share you just tell them you are just here to listen and absorb and you may share next time. I have never been to a meeting where someone was made to share.
