I know that AA has helped a lot of people, but I do not us AA for my own reasons. I have found other support that works for me.
Your friend is pressuring you about it and encouraging you to go because it has worked for her and probably want's the best for you. If she is a really good friend I would hope that you would be able to talk to her about the pressure she is putting on you.
Just my thoughts, but I do believe that we all make our own choices. That being said, I believe you can recover and stay sober without AA, but you do need to find what will work for you.
