I was done with partying when I was in my twenties, honestly. It doesn't give me anything. I can't hear people talking, we always lose each other in the crowd, it's stuffy, people are obnoxious when drunk, etc etc etc, blech.

I much prefer a social thing at someone's house with at most like 5-8 people, maximum. Preferably max 4. Then everyone can be heard, get a chance to speak, not too loud, bathroom close at hand, cheaper drinks that don't empty your pockets, access to more fun things not available in a club/restaurant like video/board games, movies, etc etc etc.

Drink more, be the puker.

Also, in re: being overweight and not being able to use apps... I'd strongly suggest you work on changing that now. The longer you wait, the harder it's going to be, and being overweight makes being old really hard. Hard as in, knee, hip, and back damage. Trust me when I say that getting into a solid diet and workout plan is not fun, but being fit and losing weight is much easier than dealing with the long term consequences.

I took a long break during the pandemic because my gym refused any safety measures (shockingly, a lot of people died from covid-19 in my town /s), and getting back to the kind of levels of fitness I had in 2018 is hard and painful.
