Sorry if this is common knowledge, but I'm just now learning this. 

I noticed my anxiety spiking today and couldn't figure out why. I also felt like my coping mechanisms weren't helping me. I suddenly realized I was listening to support calls for work AND browsing reddit at the same time. I wondered if splitting my attention between 2 activities was making me anxious, and after a Google search, I think I could be right: [https://www.psychologytoday.com/us/blog/artificial-maturity/201701/the-unintended-consequences-multi-tasking](https://www.psychologytoday.com/us/blog/artificial-maturity/201701/the-unintended-consequences-multi-tasking)

So yeah. If you're feeling especially anxious, try focusing on one task at a time. I know this isn't possible for everyone (some jobs require multitasking), but if you can, maybe give it a shot.
