Morning all!
Johnny, looking backwards in regret is likely to cause depression while looking forward into the unknown can provoke anxiety.
Although it's hard, perhaps the best route is to try to make the most of the present? Almost every present situation can be improved by applying a positive mind set to it.
That takes plenty of will power and you really need to want it. I find it hard because, I think, like many drinkers/ex drinkers, I actually feel pretty comfortable with depression.
Something I'm working on. Have a think about it
