Realistically, we all fall someplace on the mood continuum. From depression to mania, we all reside somewhere on the scale, somewhere between the extremes. To think of it in this way, removes the stigma and shame. I don't think its just "feel good" explanation but a truth. Some experience a higher "high", some a lower "low" on the scale. Medication, stabilizes mood and keeps folks in a more neutral position on the mood scale that every human occupies. There is no shame.
