Stop obsessing over the specifics of your drinking and who notices or how long it may go on and look around it: what are you drinking to escape from? What is it that instead of doing you drink? What about your life is so uncomfortable that you are drinking at it?
The answers will be long and complex and they’ll keep coming for a while.
I suggest journalling, self-help and if you can afford it and really want to change: therapy.
You only need to ask yourself this: do you want to change, yet? For me, when the pain of staying the same truly became greater than the pain of change, I did it, I moved. I was stuck in the same place for a long long time just like you. Change is possible and will happen. Prepare the soil for it, ask yourself the right questions.
