Something that compounds my ADD and is probably a large part of why it created anxiety in me is I have dyscalculia (dyslexia, with numbers) and one of the symptoms of this is audio processing. I have a delay in processing the things I hear. Especially through speakers.
It's why I hate talking on the phone. Why I insist on watching things with subtitles.
If I'm talking to someone with full headphones (not a single earpiece) and there's limited background noise and they speak clearly, I'm fine. But if there's noise or they mumble... Nope. I'm really grateful for my new coworkers, actually. They've been really cool about being willing to take or make calls (unless, y'know, we're too busy and I have to).
But it makes talking on the phone really, really hard when you have to force yourself to focus on one. single. thing. And then even when you do......the chances of making out what you've heard are really low.
I had to take a call today at work and it was for making a temporary badge and I got the name right except for one letter (f not s!) and I actually had a little celebration for myself.
For some people, talking on the phone while multi-tasking is no big deal. For me it's next to impossible. I can multi-task otherwise really well (when I have to run the SOC solo, that's 8 monitors to watch and handle information on and I love it because my brain runs high speed). But you add in talking to someone on the phone (in person is fine!) and I just become a bundle of nerves.
This is why, I think, I had my major nervous breakdown from working in a call center. It's not 'just' anxiety. It's anxiety born of this processing disability that's compounded by my ADD.
