I don't think it has anything to do with impatience...but rather on how to handle a hurricane in your work environment. I am confused. You are moving into a single office right? If the answer is no, then move. It doesn't sound as if the fellow is ready to return to work and doesn't need a facilitator to help him function at work....you have the right idea. He needs better mental health care...so he will function better. Don't let him become your problem again. How can you work on your own if you have him dragging you down?
