It's evident that women are created softhearted, which makes them exposed to anxiety and depression easily more than men, as most men are strong-hearted, and they're able and capable of tackling any difficulties and problem that comes their ways, even during depression, they manage it well. Nonetheless, during external disorders like alcohol and antisocial conduct, men are easily exposed to them because they believe, they're strong and they're meant to behave strongly either morally/pro social or immorally/anti socially, but women on the contrary, their anxiety hinders lot of them from partaking in it, because they believe, their pride and dignity is meant to be held with utmost priority.
