I suffered from PPD as well, and I agree that exercise helped massively.  It didn't cure mine fully, as my PPD was moderate to severe (I had to take medication) but without exercise, I don't think my full recovery would have been possible.  These fatasses should eat better and move more. While PPD can linger, it's just common sense to seek therapy at some point, rather than try to get pity on social media. Happiness doesn't come easy, most have to work for it.  Having a healthy body is a good foundation for a healthy mind.
