Welcome X,
I'm also 25. I'm excited about being sober even though it is difficult. I've tried to quit a few times and each time after a little while I would decide that there wasn't anything wrong with me and I could have a drink. This time I know that being an alcoholic is part of who I am and it won't change. It is actually really freeing. This time I don't have the pressure to prove to myself that "I'm fine." I'm not fine. I can't have one drink but I'm free and happy today!
I hope you find support here on your journey! Welcome!
