Statements like this need to be worded very carefully. In many people's minds, saying something like "most people don't need antidepressants" quickly becomes "antidepressants are useless". Many people who may benefit from them get scared away. Speaking as someone who has been on/off antidepressants for GAD+OCD for the better part of a decade, I've had countless people tell me that antidepressants are useless and just…
This is not something you can claim. How could you possibly know that the SSRI is responsible for your recovery?
I'm not going to say that antidepressants are useless, but it is important to understand how placebo works. The key point is that placebo works and it is impossible for an individual to distinguish between a placebo and a life changing drug.
In antidepressant studies, SSRIs often outperform placebo to a degree. However, the placebo group has an excellent recovery rate! That means there are people who are clinically depressed, suicidal etc. who are then given a sugar pill as part of a study and make a full recovery.
>You often need to try 2 or 3 different SSRIs
That makes it even murkier. SSRIs take a long time to work, and if you try several of them that's going to take months to years. There's a high probability that in that time, you might naturally recover. You have the combined benefit of placebo and waiting in addition to the effects of the SSRI. You tried 2 SSRIs that didn't work. What makes you so confident that it was the third?
Again, I'm not saying SSRIs are useless. But it's important that we rely on controlled studies to make these determinations. Personal experience and anecdotes are beyond worthless; for example they are the reason why homeopathy is a $20 billion dollar industry even though it is actually provably useless.
