Hi Charlotte and Welcome!
I'm glad you found us. To me, it's not such a big deal if you label yourself an alcoholic or not. If alcohol is causing problems in any part of your life, then it's a problem. If you're not sure, you could stop drinking for a fixed period of say, 3 months, and see what happens. You'll probably get your answer.
It's understandable that you're reluctant to accept that you will not drink anymore, so try to just focus on the day and get through things. I also didn't announce that I was stopping drinking because I had done so and failed numerous times. So, I just did it and it was the best thing I could have done.
