Very true sir. Anxiety is not the same as an Anxiety Disorder. And sorrow/sadness isn't the same as a depression...
As I see it, the problem is that when some folks are depressed, regardless if there is good reason for them to be so, they often turn to meds to solve the problem. Obviously when someone is clinically and chronically depressed without good reason like a death or loss of somekind, they need help and in those cases medication may do the trick.
Additionally, I know first hand that anti-anxiety and antidepressants can help a person navigate a rough patch in their lives. However, at somepoint, at least this was the case with me, they don't need the meds any longer.
The same is true for anxiety. There are often real solid reasons to explain temporary anxiety. However, when people suffer chronic anxiety, again drugs can help combat this problem.
I also think that when folks suffer these illnesses, they should seek professional help and not just rely on drugs alone to do the trick. Sometimes, there is an underlying problem causing their out of whack feelings.
