Confused . . .

Why is the opinion that anyone who takes medication for mental disorders such as depression or attention deficit disorder is “weak” as common as it is? Are people who take medication for a physical disorder weak as well? Now, I know some will point to instances where someone is medicated for either minor or non-existent problems, but the same happens just as often for physical disorders. Yet there seems to be a significant bias against anyone who’s going through suboptimal problems that can be corrected through the use of medication as being “weak”.
