Girlfriend confronted me about my drinking. Now worried about my future.

Ive been lone drinking for about 18 years. My idea of a great time is to boot up a video game and drink about 7-10 beers over the course of the night and try to escape to another place. I'd typically do this 1-3 times a week. This would fluctuate.

Recently I took a week off work and every afternoon about 17:00 I'd crack open a beer and start my night off. My partner of many years had been coming home from work during this week and we'd have some dinner and then she'd head off to bed as she could see what my plan was. Finally after a few days she came through the door, looked in the bin and saw a couple of cans and confronted me about the drinking. Telling me how she was concerned about the amount I drink, about my health and she asked if I might be skipping out on doing other things so I could stay home and drink.

Basically she called me out completely and it made me feel awful. She was obviously 100% right to do this. I think I had already come to terms with myself that I'm an alcoholic and needed to fix things years ago but this event really woke me up.

I know that if I carry on this way I will ruin this great relationship I'm in, continue to ruin my health and isolate myself more and more.

I suppose I'm just worried that I don't have the strength and willpower to fully stop drinking and need any advice that could help so I can start living a better life.
