I've felt for a long time that I am not fit to survive in this world. It's hard for me to end my life based on a feeling. I know feelings come and go.I need facts, measurements or logical reasoning to make what might be the most important decision of my life, if not just the last. I do believe we have a psychological immune system. In extreme cases people can completely block out traumatic events. This serves a function. It allows one to retain sanity and lead a normal life. Like other traits some are born with very good ones some are not as lucky. Differences can be caused not only genetically but from environment as well. Questions arise- was I born with a defect, was I damaged in a way that can be fixed and if not what then? I have tried to fix myself with therapy and drugs prescribed and illicit. All my efforts have eventually been disappointing. Am I fit to survive in this world? Would a depressed caveman fare as well as others or would he be most likely the first to be eaten by the bear? Is a depressed persons survival rate higher now because of technology? Perhaps long ago my death may have had a benefit for my clan. Now my life seems miserably long without purpose.
