- Apathy, social withdrawal, weight loss

Call Your Doctor About Depression If:
- You or a loved one have suicidal thoughts, or have other signs of either major depression or dysthymia; help is available.
- You are considering alternative or complementary treatments for depression. It's important that your doctor be aware of all aspects of your treatment.
NOTE: There is a distinct difference between feeling just sad or "depressed" and having a “clinical” depressive illness. If you have low spirits for a while, don't necessarily be concerned. However, if you feel you can't lift yourself out of your misery, or begin to notice other physical symptoms such as changes in sleep, appetite, or energy, seek help.
