I feel this way often but I'm almost afraid to stop working that I would just end up in my recliner all day not doing anything productive. If we don't move maybe we won't hurt as much. I'm sorry you are feeling this way about your job. Know what this major of a decision is yours because it is true that most people have no idea what it takes to get up and get ready to go to work. I wake up two hours sometimes three before I have to leave for work because I am hurting and moving so slow. I hope you work this out for what you need for your life. I know it is hard for others, including family sometimes to understand.
Please take care.
