I feel like the stress of being perceived is exactly what drives me to need to be masking all the time, but when I am able to start my hyperfocus I stop noticing the perception as much. I think it's moreso the actual masking that drains me. But now that I think about it, I remember living with my family and how I would get stressed when other people were awake because they might come to my room and try to talk to me so I ended up doing most of my work at night so I wasn't keeping my mask on standby to use your words. I ended up being pretty much nocturnal. I don't think my awareness of the sounds in the house were quite as acute as yours but it was definitely a Thing for me to be bothered by noises in the house when trying to focus, especially when near burnout. And honestly I feel drained just by being in public, even without interacting with anyone. It's probably a mix of both.
I can relate to a lot of what you've written here though. I mask all the time, I don't really know how to stop, but it just leaves me completely wrecked after just a few hours of doing it.
I'm working on finding ways to maybe not unmask, but find more sustainable lower energy masks with safe people. Part of that I guess is finding more safe people. I can pretty much unmask with my partner, but that's taken a long time to get there. I'd like to be able to spend time with more than exactly one person without burning all my energy on my dumb mask.
IRS Direct File was just a free government-run alternative to the tax filing programs like TurboTax.
You can still do your taxes by hand without the help of any software for free, but they've killed the website that fills out the forms automatically and the manual process is significantly more complicated.
