You know what my worst nightmare was? Depression.
I view those who discourage people from taking their meds as the same as people who encourage alcoholics to "just take one drink."
In some cases doctors over prescribe to people who are suffering from situational depression, giving out medication instead of treating the root cause and finding a way to tackle the problems in somebody's life, but for others it is a medical complaint. Without knowing which category somebody falls into its grossly irresponsible to tell them they shouldn't be taking medication which in many cases quite literally keeps them alive.
