Footsteps is definitely more effective than 100 people over the last 12 years, I personally know at least 4 married women who joined, and I don’t even live in new York!
None of the women I know committed suicide, but I wouldn’t be surprised if depression was a factor.
I think we need to do some work on minimizing the stigma of mental illness in the frum community so those with depression don’t have to leave to feel accepted.
