If you look at the meta studies, jewish men (but not women) have a slightly higher lifetime prevalence of depression (8.2%) than non jews (6.5%) but other personality disorders like bipolar, which are what we are really talking about here, jews are lower than the general population.

And the higher depression was entirely explained by lower rates of alcohol abuse among jewish men, since studies show that alcohol use has an inverse relationship with depression. In Los Angeles, where the jews drink more alcohol relative to other areas, the elevated depression completely disappears.
