It amazing how fast we can revert to old behaviors. I had an insecurity meltdown a month ago and I've been sober for over 3 years.
What saved me was talking to other alcoholics both on a Sr and in person. I had to remind myself that my insecurities wouldn't kill me but that alcohol would.
I was reminded that the situation was temporary and would pass. I was also told what other people think of me is none of my business. All of this is easier said than done I know. The thing that helped me the most was to take the day at a time and not drink.
We have to learn how to live life on life's terms n roll with the punches
