To this I offer a very simple thought to make you a little happier:
Nobody's yetzer hara is depressed, sad, or upset. The yetzer hara doesn't really have that capacity. Which means, that every Jew out there who is sad, that very sadness is an expression of their neshama-eloki their Godly soul.
In simpler terms, it's only because of their tremendous spiritual level that they are so low.
