Can’t talk when overwhelmed

I don’t know if this could be related to Aspergers, but I did have a language delay when I was really little and this is something that’s affected me my whole life.

So like the title says, sometimes when I get really upset or angry, I just sit there in silence. I was at my therapy appointment with my mom yesterday and we talked about this a little, which is why I’ve been thinking about it. I got in trouble for it back in school, and my mom had to explain to some of my teachers that it was part of my disability, and they still didn’t get it and said “well she’s going to have to speak up.”

And it also happened a couple of times at my old job, the manager was honestly kind of a dick and would always get mad if I asked for help or if I didn’t do something fast enough and complained about how I didn’t work as hard as everyone else there, and that pissed me off so I just went silent and then got even more mad about me not communicating.

So anyway… does anyone else have this problem?
