I would say give it time and perhaps you will get the courage to change the other things that you think need changing.
You have gathered the courage to change your drinking habits and that has been positive for you.
When I have what appears to be an impossible task I try to break it down into smaller doable tasks that lead to a positive outcome.
For example if my house was falling apart instead of giving up I would take one small, thing, like painting one room, and do it then move on to another small thing, like carpeting a floor until I was ready to tackle some of the bigger issues. It takes longer to get to where I want to go this way but I get there eventually.
I know that this isn't exactly what you are talking about but I hope it helps in some small way.
