Don't take this the wrong way, but I think you're looking for someone/something to blame for your insecurity. Women and men, as a whole, vary in strengths and weaknesses. No gender is indisputably stronger or weaker than the next. The fact that you are depressed and unemployed has very little to do with the fact that you're a woman, and has a lot to do with situational circumstances. Hold your head up high, and treat yourself as you want to be treated. Realize that you are just as important, and just as strong as any other man out there.
We're the ones who have to shove babies out of our privates, after all.
