I think it has more to do with the fact that girls often, not willing to generalize, but oh well... tend to be more open than men, like they have a problem and always talk about it with trusted friends or family, while most men, me included, tend to keep all the feeling deep inside to ourselves and no one ever knows what kind of hell we are passin through and how sad/angry/lonely/whatever we feel.
Keeping it to ourselves is really hard and it ends up in a big deppression, wich again we keep to ourselves and we end up going nuts and jumping off a window crying 'LEEEEEEEROOOOY JEEEEEEEEEEENKIIIIIIIIIINGS!'
