Freudian....
I have no idea what your background is, but your constant emphasis on 'find out what is the real reason for your depression and get it fixed and then you will not need to take antidepressants anymore' etc etc is a very narrow perspective.
Depression can be a VERY complex condition, with multiple causes. Oh, I know, there are a hundred trashy films and books where someone finds the One Real Reason why they has got the Depressions, and there's a lovely climactic scene and breakthrough, and wahey! They are Mended and the Depressions have gone!
But in reality... it ain't that simple. Chronic long term depression for example is a total bugger because the causes and effects of depression feed off each other in a horrible cycle - low mood creates negative thought patterns creates self sabotaging behaviour, which guess what? lowers mood. And on it goes.
There is often no big single narrative reason why someone gets depressed. And taking anti depressants doesn't STOP you from getting to understand your own mind and behaviour better. I could never have talked to my first counsellor without the help of anti depressants. I was catatonic, I couldn't speak because choosing any words was meaningless. Anti depressants gave me a tiny breathing space - stopped me from bumping along the bottom just long enough to look up and make an effort.
I'm not taking anti depressants now because I'm not depressed. I can't guarantee I will never be depressed again (statistically, it is likely I will be) - and if I need to take anti depressants again, I will.
Your hypothesis that they somehow stop people from getting to the 'real cause' of their depression doesn't stand up. I think you shouldn't imply either that people who have recognised they have depression and taken the difficult step of asking for help are somehow burying their heads in the sand about their condition. Not true. Those are the depressed who will not recognise their illness, do not or cannot ask for help, often self medicate and are high risk for suicide. It's them you might want to worry about.
