Hi Jade. Real simple insight here. You mention your a weight control freak. Your reasons for drinking, like mine are also about control. You use it to control time (make it go faster) anxiety (calm it down) and feelings (numb them). For many of us alcohol is a about controlling our moods or feelings until the day comes when we start losing control.
Staying in an unhappy marriage and working long hours as well as doing the house cleaning all yourself are other signs of control issues. For me, control issues stem from an inability to trust.
Willingness to learn acceptance, letting go and trust may be a direction for you to look and as Smacked said, I'm sure there are AA meetings in your area. Lots of people waiting to be your friend at those meetings.
Your in the prime of your life, time to start enjoying it.
