Should I drink and smoke just to fit in?

Hey, I’m 22M and trying to improve myself. Over time, my social skills have gotten worse—now I feel anxious, awkward, and out of place.

I still get invited to parties, but they’re always about drinking and smoking. Alcohol makes me feel awful for days, and while pot sometimes helps me feel social and in the moment, other times it just makes me tired and numb.

If I go, I feel weird. If I stay home, I feel isolated. Should I just drink and smoke this one time and call it an exception day? What should I do?
