Why do you think we need depression treatments?

After everything mankind has gone through to develop technology to cope with our weaknesses and to improve our lives, you would have thought that the world would be some utopia but of course this will only happen if humans wouldn’t be humans anymore. Despite our strive for perfection, we seem to be less happy through the years because we are also making our life so complicated. Why do you think we need depression treatments and teenagers are now even contemplating suicide? We must have a balance of everything and man should understand that he cannot live alone. Sometimes going far away from technology and just being free is the answer.
