If you are to remain sober and be happy about it, you might have to set up some boundaries with your friends and even to make some hard choices
I do not go around (never have) with a "party crowd" and other people drinking normally or smoking a joint does not bother me but I had to do a first, second and third step over my best friend who is also an alcoholic.
I also set up boundaries with him. When he drinks, his calls go straight to voice mail and I will not hang out with him. He is my friend I love him but I cannot afford to be around his disease. This was especially important for me since I am a double winner (Alcoholic and a codependent).
My first time in recovery, my partner at the time was a raging alcoholic and I ended up having to go to Al Anon to save my sanity. I remained sober through the ordeal but the relationship ended. Had I known what I know today, I would have dropped him like a hot potato the minute I saw him in active addiction.
Anyway, congratulations on staying sober and on day 13
It will get easier
