picard- I hope you'll take bwaites' advice to heart, and ESPECIALLY pay attention to his P.S. It's clear that the folks who've responded to you mean well, but the fact is none of them knows enough about you or your situation to give any specific advice. General advice- exercise, talk to your doctor and/or a psychiatrist, consider switching drugs, don't stop cold turkey, don't give up- that's great, but we really can't tell over the forum if you have a situational depression, major depressive disorder, bipolar disorder, anxiety disorder, or what. Advice to switch to this drug or that, or that you don't need a drug at all, should be taken for what it is- an anecdotal account of what has worked for one specific person and may not work or may even be harmful for you. It is very clear that antidepressant medications, properly prescribed and monitored, have greatly improved the quality of life for many people, and have literally saved the lives of many others.
Having said that, here's my general advice- don't give up, and don't feel guilty about being depressed. There is effective treatment, it's often just a matter of trial and error to find out what works for you, whether that be mediCation, mediTation, counselling, or a combination of things. And, while it may very well be that bad luck in looking for a job has you down, please keep in mind that depression is a chemically-mediated neurotransmitter disorder, NOT a character flaw, and you can't will yourself out of it just by saying to yourself that you don't have it so bad. Best of luck to you.
