long periods of time segregated lead to me thinking. me thinking is bad, bad bad bad bad bad. when i think for some stupid reason i think of questions that don't have answers, when i don't have answers i get depressed.
now throw in the fact, when also isolated, i over analyse usually meaningless sentences said by people. imagine thinking about one sentence not for hours but for three or four days, and being isolated you don't get answers to the question you are looking for(mind you there is no question) and this leads to further depression.
no mix this all up and you get i nice big bowl of ' i depress myself, i segregate myself, pretty much i fuck my life up as much as i humanly can' soup.

wow that relieves the senses a bit.
