The literature may help others. I been sober since October

The literature may help others. I been sober since October 2019, since then I have held a grudge against the substance. My substance of choice was alcohol, I see that shit everywhere but it Don't bother me like it use to. Its like having that ex that hurt you to the point where you get angry whenever someone even mention its name

What did you do to overcome the resentment? Your solution may help someone else here.
