What's with these commercials?

Ok, I’ve noticed recently that commercials that are promoting their products seem to just make you feel worse. Of course the ASPCA commercials are extremely sad, for a reason, but what about those Cymbalta commercials? “I felt like I just had to wind myself up everyday”. Don’t people suffering from depression want to see happy people (even if it’s tacky and sugar coated happiness) who have taken Cymbalta, and whose lives have changed etc… Do those suffering from depression really need to know how depressed that person was, what depression was, and how they had to “wind themselves up everyday” because they were so depressed?
What about those Orajel commercials? People are basically screaming to you through the screen about how they went through excruciating pain from their gums. Sometimes I find these commercials quite funny….and weird. So, what do you think about them? Are there any other commercials out there that you feel the same about? This is a completely random question that just popped into my head one day, and I just wondered if anyone shared this same feeling with me or if I’m just going insane.
