I do genuinely see where you're coming from and, yes, you are almost certainly right. I'm just say that it is much easier for someone who doesn't have the condition to hold such views in principle than it is for them to put them into practice. If you would be prepared to sit down and talk to everyone who said they suffered from depression in order to establish whether or not there was a medical basis for it, no matter how long a day you'd had or similar, then I have absolutely no problem with what you're saying.
