There's no rule that you have to do a specific amount, the same amount, at the same time, all at once, every day. Just break it up and relax. Take a quick break from work in the mid-morning and walk outside for 15 minutes instead of drinking coffee. Go out for half an hour (or whatever) at lunchtime, go for another 15 min break in the afternoon instead of more coffee. Occasionally invite a coworker to go with you. If you can discuss business (on occasion) you can keep working while you walk. Then another 20 minutes in the dark after work. And some days less, some days more, and extra on weekends. The requirement to obey strict walking rules will end up CAUSING the anxiety it's supposed to relieve. Just make it a fun break and take fun breaks here and there when you can.
