Did you bring some means of stimming or finding comfort?

I don't exactly suffer these scenarios the way you seem to describe, but I feel a lot of it to some degree, and bring other issues to my day.

I find stimming really fucking helps me. When I was a kid, and it was socially acceptable to do so, I'd press into and hug my stuffed furry animal in my bed, and I'd feel a lot better. I do that with my bedding sometimes now, it still comforts me. (Thinking about just ordering another stuffed animal and not giving a fuck, what's my autistic roommate gonna do? Make fun of it? Probably not lol)

Today, I had an unexpected visit from a coworker, he stayed unaware, but it stressed me the fuck out, his projects were done, so he's here to help, I can't rightly tell him to fuck off, I implied others likely need his help more, repeatedly, but nah, he didn't want to help them...
I spent a lot of today stimming, like a lot, he knows I'm autistic, so I just did it lol. But doing it fucking helped. I wish he could read into why I'm stimming, I can't seem to tell him, "Hey, that autism thing, your unplanned presence is aggravating it."
