Distinguishing these efforts from real problem solving is important. Anxiety may be either silent or actually expressed and is likely a very realistic fear of an unknown and probably difficult future. It is a very natural response to change and people should not be made to feel stupid for having it. Giving people as much information as possible is the best antidote for anxiety. It is often coupled with a sense of sadness.
Depression includes feelings of being down, flat, hopelessness, and being tired a lot of the time.
Even though it is hard to be around depression, you can't make it go away for somebody else. People have to go through it, not around it. It is important to make clear that we understand when folks are in this state, and yet work still has to get done. Having ways for people to experience some influence on their situation can also be important. As the change progresses, people begin to make the transition to a testing period.
