I'm feeling extremely depressed about growing older lately. I don't know what to do?

Get help. There are /extremely effective/ treatments for depression, and depression is especially dangerous in older people. Please read this information http://www.Nimh.Nih.Gov/health/publications/older-adults-depression-and-suicide-facts-fact-sheet/index.Shtml and see your doctor, a clinic, or emergency department if you are feeling helpless and hopeless or are having any thoughts about harming yourself.
