Cynicism and depression are two things that instantly destroy the humanity inside a person. The rejection of reality or the recognition of one’s powerlessness to affect or change the reality can have one question his or her capability as a person. Humans are built to function through instincts and ideals, but being unable to do these things can make one question his or her own sanity.
Cynicism an ideal left unfulfilled because of a harsh, uncontrollable reality that blocks the ideal from being achieved. Oftentimes, this is through human limitation, which the idealist gives up because it is beyond their means of understanding. This is where people would often say the line that dreams do not come true.
Depression on the other hand is when the human limitation takes hold of a person and he or she believes that they do not have the capability to become who they want to be because of an impossible obstacle. This may be similar to cynicism, but it is emotionally affected.
The only solution to both things is to make the person believe that they have the will power to survive and still understand the world. Making them recognise they only lack the tools, but nothing is wrong with them, is the key to overcoming such obstacles. It is similar to a difficult literature problem; when you have not read the book or have any other literature to compare your report to, you do not have the tools. You have responded well, but your response is not found on solid ground, which tools can provide.
There is nothing wrong with you, but the method must be wrong in itself.
