Hey, funbuchur! The first thing the get yourself going each day is what you’re already doing .
The incredible accomplishments of more than two months of hard work are still there. Yes, you still have work to do, but as HHM said, you’re still high on the mountain. Your life is different. You’ve learned that you can live clean and that you want to. That’s tremendous. The fact that you fell does not mean that those facts aren’t true.
So, the first step is to stay on up on the horse for a good few days, get back into the swing of things.
After that, I think that there would be value in analysing what happened that led to your fall.
How were you feeling that day? what events (external and internal) were taking place that ended up leading to the situation that you found yourself in? There was a slip a few days before. What led to that?
Honest introspection can lead to the gift of greater understanding of what role this stuff has played in your life. How you have come to use it as an antipode for stress, pain, anxiety or feelings etc. Of you achieve insight, you can use those understandings to fight harder, to change better.
But for now, you’re a warrior! Here’s a hand and a hug.
I admire you,
Chaim Oigen
