Go to an AA meeting. There are people there who you can relate to. There's help available. No one will judge you. No one will criticize you. Lots of us have been where you are. Lots of your friends, neighbors and loved ones know or suspect you have a drinking problem. It won't be news to most of them. It is already pretty bad.
Having said that, everyone you meet in AA won't be a pleasant person. It's a cross section of society, like lots of places. The only thing we have in common is a problem with alcohol.
We also have a Tradition of anonymity. That means we don't use last names, yours or ours. We don't ask for or give identifying information. If you see someone you know, they'll be just as anxious as you are that nobody outside AA knows either of you were there.
As a newcomer, you will be welcomed and offered help. Please go. Today.
It's worked for me for over 23 years.
