First of all, this hormone is called dopamine in Russian, so you immediately suspect that you have read something from people who don't understand a damn thing about biochemistry (although I may be wrong, and you have read an English-language source).
Secondly, it is produced in the brain, and works as a neurotransmitter, and in the adrenal glands, and works as a hormone. These systems are quite well isolated, and intersect poorly.
What is meant by “restore” and “abyss” I understand poorly.
But you're more interested in dopamine as a neurotransmitter than a hormone. A lack (or rather an overabundance) of dopamine in the brain, yes, is associated with behavioral and mood disorders. But it can't disappear at all, your brain will stop working.
As for the hormone, it also can not disappear, if your adrenal glands are not dead. But if they do, then dopamine isn't your biggest problem.
