One of the really difficult things with being both neurodivergent and trans is that I’ve learned to mask both, but I didn’t know about either when I learned that masking.

So in certain social situations, I put on a version of this mask that’s not only draining to perform, but also actively makes me feel worse by making me act more masculine.

Like just now I had to call a technician to fix a problem with my house’s HVAC system, and as I left the message, I’m mimicking how I’ve heard people in those sort of jobs talk when they leave messages and how my dad leaves messages for people like that, and in doing so, I adopt a very masculine way of speaking, while inside I’m simultaneously panicking about:

remembering the information to say

remembering what the words for things are

trying to sound competent and match social expectations (which i only have a vague idea of)

panicking that i paused too long trying to find a basic word a second ago

trying to maintain this false confidence while starting to have a mini gender crisis in my head as I hear myself talking so masculine and manage to somehow simultaneously experience gender dysphoria and doubt that I could sound like that and really be trans

And all this while also knowing that I’m going to miss his first call back because even though I added the business number to my contacts, he’s probably going to call back from his cell phone.
