Mental Instability

For some people it is necessary to be protected from anything that might create excitement, emotions too intense in order to maintain their mental health; Fatigue and poor physical condition will push the person in madness even faster if this one is exposed; I think mental instability and hypersensitivity go together very often.
(the writer Virginia Woolf is a good example in this case!)
(All mental problems, called "mental illnesses" by the experts when the problem prevents the person to live and function in society, are to me simply chemical unbalances in the brain, here from birth or developed through the "conditioning" of our lives; Obviously the so complex brain is still a terrible enigma even for the more advised scientists who study this organ; Mental illnesses are still taboo!; An obscure and frightening subject for most people, because the unknown, the mysterious (due to a lack of knowledge) creates fear in humans who do not want to make the effort to gather informations to understand and just... think.
