It is perfectly natural. Try taking some social animal like a bonobo, and sticking it in a horrible cage in solitary confinement, and maybe poke it with a cattle prod now and then for extra measure. Do you think it's going to be a perfectly happy little ape? No, it's going to become morbidly depressed or disconnected from reality. There's nothing wrong with the bonobo; the problem is with his environment. The bonobo doesn't need anti-depressants, he needs to be put back into his healthy bonobo society in the forest and not kept in a cage and zapped with a cattle prod. Most mental health treatments are just band-aids, just like dosing a tortured ape on anti-depressants so he doesn't have to deal with the suffering he's being forced to endure.
