@cdlara381 My relationship with alcohol is: why should I consume bad-tasting poison that makes it harder to think straight?
If I want to be a 'fun' social person, I will get myself into the childlike headspace of being outgoing, friendly, and usually entertaining (aka attention-seeking). Usually I need to stay present and go with the flow. It doesn't work if I'm not feeling comfortable or positive, so some kind of mood-boosting, energizing activity beforehand, like exercise or singing, can help with that.
The first step to adopting the right headspace is either letting myself be openly curious about people, or be willing to talk about myself and my interests. This also works in day-to-day social interactions as a mode I can adopt to make people feel appreciated.
If I'm not feeling particularly social, and there's a significant music presence, I can always start dancing and entertain that way. If I don't feel up to entertaining anyone or making new connections, I likely won't bother attending the social thing.
