A. You need to define what you mean by depression. Clincal depression is one thing and feeling low from time to time is another. There is a lot of good information at your finger tips on the www. You may want to shy away from those websites that are paid for my the pharmacutical companies. They want to sell you their drugs. What is the cause of your depression? Are there one or two things that you can point to? If you are clinically depressed, see a dr., that is, if you can get out of bed...If you are depressed due to family, or the fools in Washington, those are things that you may work out with your minister or rabbi or a therapist. I have found a lot of good information on therapy and therapists on www.focusas.com
