Is there One thing you could get yourself to DO when not working? You may need to do it upon leaving work, before going home, or before, depending on your work schedule. Something like, take a walk (choose a route just one mile round, or a destination to "get" something non-food, collect stones, pick flowers in season, take a train or bus ride...anything), ride a bike, go to the library and peruse, depending on location, sit by water, look at art, visit a zoo or walk an animal from a shelter.......Anything at all... You need some small thing to break the cycle---
some small, other interest...at first, just some, small, other commitment. You can do it because you do go to work...you are able to get up---....and if one thing doesn't work, do another---keep it small and doable so that even if it causes distress at first, you can see the end of it each time----------take a hobby class (something short like making something in one or two sessions...) maybe use the local paper to choose one thing a week to go to or even participate in even if your head tells you how stupid, worthless, anxiety-provoking it is...
Sometimes therapy can mire us in our problems...
What sort of work do you do?
