Tell them, you cannot keep up your masquerade anymore. You need to slow down a bit. They shall accept you with your quirks when being yourself. You might insult people occasionally, but you don't mean it that way.

first of all, don't assume the worst right away. you got drunk, you got annoying, it happens even to neurotypicals. you might get scolded, you might get a formal warning, you might even hear nothing at all. you might of course be fired, but don't assume that's the only and most certain possibility right away

when you're less freaked out about being fired, think about how you're going to deal with social events from now on. assume you're not among friends when you're around coworkers and start figuring out the bare minimum you need to do to make them (and perhaps most importantly, your bosses/superiors) feel like you were present and socialized. once you feel your job is complete, leave immediately. during normal workdays, interact as little as possible with coworkers but again measure if you need to interact a little to keep your boss happy.

it's not easy and it's still gonna drain you, but remember that you don't need to appear like your average neurotypical coworker. do the bare minimum, then leave

if possible, try to spend time with or even just open up to people you care about and trust. i know it doesn't come easy to us, but community is one of the most important things for anyone's mental health

here's hoping you keep your job tomorrow and are able to keep your shit together regardless of the result. sending lots of hugs 🫂

Follow up: jep, got fired. get paid until the end of this month. Thank you for you're comments

This sounds like burnout. You need to make sure you aren't overdoing it as that's a quick way to start having shutdowns, meltdowns and poor decision making.

I would strongly recommend that you sit down in a one on one conversation with your boss. It is going to be tough explaining what's going on but I would start by telling them that you are just feeling really burnt out. Don't raise your voice and speak slow and calm.

That event with your coworkers where you got drunk; you touched someone inappropriately, didn't you?

Because you are being purposefully vague, I'm not sure it's because you harassed someone or not. Many reasons to fire someone, but very few reasons to suddenly fire people immediately like what happened to you. So this makes me suspicious.

So, OP, confess. What the fuck happened?
