You sound very similar to me. I too train in the gym almost daily well only when I'm not hungover but I keep myself relatively fit. I on the other hand spent all my late teens twenties partying and binge drinking. Of late it's become a lot worse I haven't kept my drinking to weekends I could go out any night and binge heavily. I never have problem functioning in work although I do feel like I'm on deaths door. Alcohol has resulted in depression, anxiety, isolation and broken relationships because I would never leave anyone see how bad I felt only my ex girlfriend. To the outside world and my family I was having a great time. My family didn't know the extent to which I was drinking. I finally admitted it to them two days ago and I'm hoping I can sort my life out now for the better. The people on here are great help to me in the last few days I'm delighted I stumbled across this website I'm sure you will find them the very same. And hopefully we can support each other
