Welcome to SR and congrats on your sober time. You will find plenty of support here and most of us can relate to what you are feeling. I noticed when I quit that many people split. At first I was overwhelmed by the loneliness but am now grateful for it because I needed that time to myself to quit drinking, evaluate my life and also those around me. Most people around me are not alcoholics but they are types of people that prior to my drinking....I would not have surrounded myself with. I know there are so many great sober folks out there who enjoy life without the booze so it I sobriety has opened new doors for us.
Hang in there and if anyone isn't on board with your sobriety then cut them off. Sounds harsh probably but anything that may hinder my recovery must be removed.
God Bless and so glad you are looking at AA.
