From my own experience with sobriety in the past:
I treated sobriety like it was a forced situation. My mindset was that I couldnt drink and there was no other option. What has changed this time around is that I do not want to drink and my mood towards the abstinence is much more serene and welcoming. I do think that being sober needs to have a mental approach that involves positive thoughts and actions as opposed to negative thoughts and anger.
It is not an easy road but what we tell ourselves can make or break this situation. Perhaps look at your thoughts toward your own abstinence and try to see where they are feeding you negatively.
