Hello AlwaysChanging2.

Alcohol dissolves our fears, that is why they used to call bars 'speak easy's'.
But now we are in recovery. In the beginning, most of us have poor skills in dealing with our fears.
As far as I know, the best way to deal with our fears is to acknowledge them and face them, to face them is to take a risk and do what we need to do to recover.

Remember, first things first, one step at a time.

Also, the 12 Step program is a spiritual program. In other words, it is a program where our faith (trust) gets tested all the time. Have faith that you really will be okay even when you don't feel okay.

One step at a time.

If you really fear being asked to share, you can always ask the chairperson, before the meeting starts, to not ask you to share.
But do not rely on this, people forget.

A good ice-breaker is to hang around before and after the AA meeting. Try and talk with others, or be close at hand so others can include you too into their conversations. You may have to wait until they finish what they are talking about.

We need to take a risk, or we end up drinking again.

Or stay near the meeting entrance and shake peoples hands when they come in. You don't have to say anything. Greeting others is another risk exercise.

Get involved in the kitchen. Wash up after the meeting, lots of friendly people do service, like this, before and after meetings.
Trust that it will get better over time.

Take a risk.
