Eric,
I feel exactly the same way you do. I have only been back to work for about four weeks and I'm really struggling with it. I am currently working at an outdoor gear store, but have not resumed teaching my fitness classes yet. After learning that I have cancer, helping people find outdoor clothes and shoes is...annoying.
I'm sorry you're struggling with wanting to work. Did you enjoy your career before you got cancer? Do you think there is another career out there that would make you happier?
I guess I don't really have any words of encouragement. Just wanted to say that I think a lot of people feel the way you do. You're not alone. Take care, Eric.
