This is how the brain works. In the center part of the brain is where the cells that produce serotonin and norepinephrine modify the rest of the brain. Just like a  dimmer switch can control how light or dark a whole room is just from one small  area, each cell has connections with half a million other cells and you only  have 250,000 in your whole brain. 

The signal comes down the nerve, it releases these chemicals which then go  across the space called the synapse. Once those chemicals fill up the receptors on the left side of the synapse, the signal is sent. That's how the nerve on the  right influences the nerve on the left. 

Here's a higher magnification of the same thing. The signal comes down the  nerve, it releases, goes across, reaches critical mass, now sucks back up into  the yellow vacuum system. Now the body will recycle some of it, but the rest of  it is destroyed and thrown away and how much is destroyed and thrown away is dependent upon your family characteristics. 

So if you don't have enough of the chemical to fill up those receptors, then you  will have the signs and symptoms of depression and anxiety. Some people have problems with too much rather than too little. This is what we think happens with people with schizophrenia and this is the dopamine system. 

They're being so overstimulated with dopamine, they become very agitated,  they hallucinate, they can't sleep, they hear voices. So what we use is  medications called atypical antipsychotics which are represented by  these green balls which temporarily sit and block those receptors from being  overstimulated. Helps to calm them down, the voices go away, they can sleep  much better if they'll take their medication. 

Now this is what happens with depression. Chemical is released, it did not  reach critical mass, so sucks back up into the yellow vacuum system and a  double dose is now released. Now there's enough to fill up those receptors and  boom the signal is sent and now it's sucked back up into the vacuum system  again waiting for the next signal. 

Now antidepressants are not addicting, all they are are these white balls that  simply plug up that vacuum system. So now the body can't bring it back in and  throw it away, so it helps your body conserve what you've already made. So  now the concentration in that gap increases. 

It's like having instant hot water, when you turn on the spigot you have hot water immediately, you don't have to wait for all the cold water to be pushed out of the hot water pipes before you get a cup of coffee or tea. This is what's addicting,  this is in the pleasure center of the brain and these are the dopamine receptors  and these purple balls represent methamphetamine and cocaine which now  begin to hit and to smash and to destroy those receptors and it's like taking a  hammer and smashing it through a board of wood so that people can no longer  experience normal pleasure and joy in life unless you have more and more 

cocaine. So if you understand that, you understand how the brain works.
