I’m so anti Social these days

I used to do have fun and drink all the time with my friends but in recent years I became a homebody and stay to myself ...now I want to go back out and have fun with people but I don’t know how to converse or what topics to bring up and it gives me low key anxiety because I don’t drink anymore so I’m sober and not as chatty as I would be drunk ....any tips or help for me?
