There are times medication is necessary to help regulate the brain chemistary and allow the person who suffers from the depression to level their mood. I suffer from depression and reached a point that nothing work, my depression was quite servere and I wasn't able to do much of anything except work and sleep. I let it go on for far to long and was on the verge of a nervous breakdown. When I finally called my doctor I had a pysch eval and medication was discribed and my moods, my life, my stress is alot easier to handle than it was back then.
What people need to realize is that depression is a mental disorder and when you reach the bottom and can't get yourself back up medication could be the only chance of living a stable life where before stable didn't exisit.
