Since one sees the world through one's goals, this explains e.g., the bipolar affective disorder: These are also two worlds in which the client finds himself. The brain has changed each time, and so it also sees the world differently. The senses pick up this worldview and send the data to the brain.

 It is scientifically proven that depression can be inherited.

In addition, they are reinforced by goals that have not been achieved and that attack again and again (want to be fulfilled), although it is apparently possible or not at all possible for people, but they cannot break away from them.

The latter can also result in depression, although no predisposition has been inherited.

Depression is therefore usually the burden of several goals (the hereditary disposition also consists of aims), which urge you to be achieved, to be fulfilled, and not to stop - although people usually fail to do this (often despite all attempts and efforts).

People with depression have two problems:

You suffer from this disease, and often only see the negative side of the world, which their brains show them in corresponding grey colours.

As aims become stronger (in terms of the fact that they want to be fulfilled) this burden puts pressure on people.
