Welcome.
Better to try and stop now than let it carry on. I think that having identified that you are having a problem with drinking, trying to stop and deal with it now is the best first step. It only gets harder the longer you leave it.
There's a bunch of us in the August class all trying the same thing, some for the first time and some of us are returners. You would be very, very welcome to join in. We're all just trying to get through this a day at a time.
