Paid handsomely by the NHS? Really? Don't believe everything the Government and the media tells you. And for the record, there are actually 27 licensed antidepressants on the market. There aren't 4 main ones, there are common ones that tend to work better for most people. Quite frankly, I think advising people to question everything doctors tell you, is dangerous and short-sighted. They undergo 10 years of training just to be able to practice as a GP and are constantly having to train to keep up with new treatments and developments. Google is not an adequate resource. And that's the problem with depression isn't it, we're quite often not in our right mind. I haven't seen a single GP who thinks pills are the only solution; counselling, CBT, mindfulness, exercise to name but a few.
