Emily Dickinson-dark poetry

Emily Dickinson appears to write poetry that is dark in nature.  I have to wonder if she was a bit depressed during her lifetime, which may have caused her to write the way she did.  She was after all a recluse which could be a symptom of depression, either that or she was simply unsociable.  Or maybe she simply had a fascination with death, etc. that fueled her desire to write her poetry. 

In poem 764/754 she deals with what appears to be womanhood or I should say the ideology of womanhood.  In her poem she says that the woman is in essence the gun and that she cannot function without the man controlling her.  Yet, the gun/woman has more power than the man, because in a sense she can kill and not die, which would make her stronger than god and the man who believes he controls her. 
She even gives a stanza that depicts how women are below men when she discusses guarding her Master's head.  The word Master is a good clue that says she is below him.

I thought the last stanza was saying that she knows that she will out live him,but he should really be outliving her, because that is how it should be, because in this time period a man was suppose to be stronger than a woman.
Although this poem deals with death, I also think that it deals with the conflict within women.  The women, especially during this time, were suppose to be household fixture-the homemakers, etc. and yet at the same time these women were stronger than the men because they had to ensure that their men, children, and households were all taken care of.  The conflict comes into play when a woman is suppose to be fragile, yet in reality she has great strength, thus she is both when she is in the eyes of the males of the time suppose to be just fragile.

The poem brings to mind the old saying...."Hell hath no fury like a woman scorned!"  In other words don't mess with the woman, because she can be way deadlier than any gun!
