Linners,
Only requirement to be a member of AA is a desire to stop drinking. You don't have to label yourself as an alcoholic. Many people that don't identify just say that they are guests or might have a problem. It would be perfectly fine to say, "I am Linners and I have a desire to stop drinking" at a closed AA meeting. The rest of the meetings you can say, "I am Linners and I am a guest".
Good luck
