Sobriety is about you. It doesn’t matter who doesn’t understand or has other opinions. You don’t need to explain it to anyone and you don’t need anyone’s approval to get sober.
This is about you getting honest with yourself and working for a better life. Which you can also achieve if you go about it the right way. You’ll find community in AA and also here in the forum, which is a great asset. You’ll learn the ropes and develop healthy habits. Learn to deal with your emotions and so-called triggers. Develop a relationship with yourself that’s good and warm, not disconnected and twisted. And rectify your existing relationships over time by becoming a better person in recovery.
