You have taken that first step - you are going back to work that is great - pat yourself on your back. Baby steps - each thing you do tomorrow will (note the word will) be an accomplishment. Getting up - woohoo - getting ready for work - woohoo - getting in your car/bus however you get there - woohoo - opening the door to work - woohoo. Each thing you do give yourself a woohoo. One step at a time.
Hope this helps
