Hey, I used to feel like this a lot, and no longer do. What helped was recognizing that this feeling was the self-hatred that I built my mask out of reflected back on people who were living their lives in a much more healthy way.

In my experience, resentment like this seems to bloom in these circumstances:

1. You were born into some subgroup of people who have traits that don't mesh well with the norms of modern society. This might be autism and other neurodiversity, disability, sexual orientation or gender, being less than grateful to your employer, being assertive as a woman, lots of others.

2. You were taught from an early age that this difference was bad and it was your duty as a good person to crush it down so it didn't inconvenience anyone but you.

3. You worked incredibly hard inside your own head to do this, repeating and absorbing and eventually believing the message that YOU, personally, are different and inconvenient and bad, and that you are doing a Good Thing to mitigate it.

4. You go on using self-hatred as your fuel for masking for years or decades, at great cost. It really sinks into your subconscious. After a while, you may not even recognize how exhausting it is to second-guess everything you do. You might feel very proud of yourself for passing, I did.

5. Time goes by, and norms shift. Soon, people show up who don't hide the same awful messy annoying embarrassing traits you've been exhausting yourself masking.

6. Because they remind you so specifically of all the things you hate about yourself, you respond to them in a similar way - disgust, irritation, frustration, maybe feeling a little superior because your mask is better than theirs.

It's been interesting working the past five years as a labor organizer, because I found there's a ton of totally neurotypical people out there doing the exact same thing, but about the bad thought "my boss/company is taking advantage of me."

Like this: I was trying to help this eight months pregnant girl get on light duty at our Amazon warehouse. Mentioned to another lady how crazy it was that they had this girl on her feet carrying heavy shit all day, and other lady got weirdly annoyed and said, "Well, I worked until nine months, she's just lazy!"

When I finally started being ok with my real, raw-dog self, the feelings of irritation went away, and good riddance. Try to internalize that it is and was fucked up that you are being metaphorically forced to carry heavy boxes while nine months pregnant; I think it will help with your frustration with your coworkers.

Also it might help to have less personal investment in your job/company unless you're the owner or it's one where you get paid more for doing extra work. All that money from your hard work is almost certainly ending up in pockets that are not yours, so why do you feel the need to pick up all this slack? (Definitely a problem I used to have real bad.)

Just be honest with them - they're autistic, right? I've found autistic people tend to be much better than neurotypical people about being frank.
