Depression

According to Dr. Oz, these are the symptoms of depression:

•Loss of interest in things you enjoy
•Changes in weight or appetite
•Change in sleeping patterns
•Feeling of sadness, guilt and hopelessness
•Making other people feel depressed and pointless (bringing other people down)

Many people in this community have probably experienced depression. Do you agree with this list of symptoms? Would you add or remove any? Have you ever experienced any of these (presumably yes, since this is an ED community)? What did you do to recover?
