Returning to work post Max

Tomorrow I must start back to work and leave Ellie and Max at home. I do NOT want to go. I'm lucky and thankful to have Hazel here to look after them at home and make things easier for both me and the kids. I am trying to be strong, but I feel a bit detached to survive it all! It's quite sad! I wonder if we've set the wrong priorities in life by my return to work to live in this house and live the lifestyle we enjoy?
