Hi and welcome! It’s nice meeting you. Whatever label you prefer (“alcoholic” or “problematic drinker” or “I’m concerned about my alcohol use”) is ok. The point is you’re here because some part of you thinks there could be some adjustments. The first step after that is making a small change & seeing what happens.
This thread has links to a lot of resources you can explore. If you find labels a bit heavy you will find many are open to you listening for the meeting, you don’t have to speak if you don’t want to; my SMART recovery group is like that. Take a look:
Resources for our recovery
If social awkwardness is a concern for you this one is all online:
The most important thing is to be aware and to stick with it. Addiction (or problematic use generally) is about escaping, where we live in our world of running away into our addictive behaviour, because it’s comfortable and familiar. But it creates problems for us. It creates chaos in our lives. The important thing about reaching out and communicating with others in recovery, is it helps keep us aware. It helps open our eyes and see what we can change, and how to do it.
It’s a journey. It’s one step at a time. We’re here with you, and I’m looking forward to walking the path together 
Take care & keep checking in here
