It sounds like your anxiety is triggering a fight-or-flight response. If it were me in your shoes, I would tell my manager about the amount of anxiety you're experiencing and your desire to fix it, and then take the next week off or a 4 day weekend to try and decompress. If your manager is good and values you, they will be concerned and supportive, and you'll be able to fix the problem together. If you aren't physically active but you're able to be, getting into an exercise routine that either involves some high intensity cardio or weight lifting would probably be help your mental state. The trick is to get out of your comfort zone and feel physically sore from it afterwards. I felt anxious and depressed a couple years into working at SpaceX. Once I became consciously aware of it, I was able to tell my manager about it. A big part of it was poor alignment between my backlog of projects and my inherent interests. He moved mountains around so that I could work on something I was passionate about, and my last year there was a blast. I also started working out 3x a week including jogging and rock climbing, and went from being able to barely do a pull-up to do being able to do 100 in a day. After a few years at Google I was pretty jaded. I was already working on some cool stuff and liked my immediate team. My gripes had more to do with the corporate politics, and so I decided to leave to try a scrappy startup that was desperate for my skill set. I've been at Zipline for over 5 years now and it's turning into a big company, but I have very little to complain about. In 2020 I was having some legit panic attacks while interacting with coworkers, though. I was going into full-on fight or flight mode. That just turned out to be all the atrioventricular nerves on my heart failing at once! Getting a pacemaker and then figuring out and addressing the root cause solved that problem pretty well. Now I just suffer from the occasional blood pressure spike when coworkers say or do something silly, like at any company. :-)
