You can go out for drinks with coworkers and not show up hungover the next day... Like, office happy hours are basically a cliché at this point.

You do not need to get drunk, or drink any alcohol at all to have a good time. No need to go until early in the morning either...

Mentioning loneliness and then complaining about them socializing is kind of a self own

I do not optimise my life to benefit my day job.

And even if I did, socialising with your coworkers has a strong chance of being much better for your career than another early night.
