Saturn in the Twelfth House?

What does it means?

You may seek (or wish) to isolate yourself, spending much time in seclusion or working behind the scenes in large institutions. There is a lot of lonliness in this position.

Your work may involve psychology or charities, but you're most creative when you work alone. You often feel you're being threatened, but this actually stems from your own fears. The choice is yours: to serve or to suffer until you dissolve your deep-seated selfishness. If afflicted, secret enemies may contribute to your downfall or are they imaginary?

Saturn is the taskmaster and shows the house where you will have to work hard to free yourself of the inner secrets that you hold.
I have seen chart where the person's father went to jail or was hospitalized with Saturn in 12. But I do not have no other data to work on, nor sign.
Saturn in 12th makes one very very reliable and people even seem to depend on them. But where are those with this planet going to lean on ?

Saturn in the Twelfth House

Each planet in the twelfth house represents energies that an individual may be denying even exists. Saturn in this house could mean an early life setback which prompts you to push the realities of life into the unconscious. People with this position of Saturn often are plagued with guilt and it is difficult for them to know where the guilt is coming from, or even to define their anxieties. Fear of the unknown and of being overwhelmed or controlled by emotions may be the source of your general anxiety in life. It can be difficult for you to submit to the idea that you may need help from others, preferring instead to withdraw and handle your problems in solitude. The idea of exposing your innermost feelings makes you feel painfully vulnerable and dependent on others. A deep-seated feeling of loneliness and separateness can be the result. While self-control seems to be the most attractive route for you, you might find that letting others inside you, even in little ways, will help you overcome many of the vague feelings of guilt, self-doubt, and anxiety that prevent you from enjoying life in a free and natural manner. Learning to embrace your sorrow, free from guilt, is the first step towards true self-acceptance. You may be an escapist from life itself. Address your escapism. Question yourself, or talk things through with an alter ego. Make sure that you understand the demands of the real world, as well as its joys and pleasures. This will help you lead a more fulfilling and rich life.
