Alas, but depression is a disease. With it, the biochemistry of the brain changes. And the person feels, as if inside the poison is developed, which removes all colors, except black.
Enjoy life in this state will not work, no matter how hard you try. And chocolate will lose its taste.
Therefore, if you have a real depression, you must definitely take antidepressants. But when they act, start to enjoy the little things in life. Gradually the work of the brain normalizes, and it will be possible to refuse depressants.
My mind fights that it is not a disease. That's part of problem.
