I second what Batman says. Whoever thinks mental illnesses are not real, not only are they short sighted but shows ignorance and it is the sad reason why Depression and other mental illnesses get no attention from our politicians. The bulk of the work is left to charities. Robin Williams' death is already linked to depression. The UK has the highest suicide rate among young men in the whole of Europe. The numbers beat that of the opposite sex in any age group combined. There is sadness in this statistics and if you choose to pretend non of this exists then that is your decision.
