Hi JTAA,
I can relate to your situation. I too was regarded as successful in my career, I have a loving wife and a 5 month old daughter. I had a serious mental health break two years ago, which as I came to realized was related, primarily to alcohol. At that point I told everyone I knew that I had stopped drinking, thinking that by telling everyone I knew I would force my self to stop, well I didn't. It just drove me to drink alone. Three weeks ago I finally hit the breaking point with the lies, that I was telling to others and most of all to my self, and I came clean, I'll admit that though my wife suspected that I had been drinking, but had bought my lies. We as addicts are really good at lying.
Needless to say that is a really hard first step. But It allowed my to start to move forward with my recovery. I've spent the last two and a half weeks in an alcohol withdrawal management program. I'm both humbled and thankful of the support that I receive there, and most of all being able to share these things with people who are going through/have gone through the same things.
The important thing is that you are here and that's a big first step, but something that I've realized over the past three weeks is that we are responsible for our own recovery but, we don't have to do it alone. I hope that you will find some strength from this site and I would encourage you, like what Dave said to look for more help. AA, a day or residential addictions program, or one on one addictions counseling.
Wishing you luck in your recovery.
