Twilight Zone

So, I've been reading the Twilight series and I have to say I'm just not as in love with it as everyone else seems to be.  At first, I couldn't figure it out, but after finishing the second book "New Moon,"  I think I've put my finger on it.  Bella is the ultimate girl who doesn't realize her worth and value.  She sees Edward as being so much above her that it is somewhat sickening.  She sees herself as this homely, pathetic excuse for a human being when it's clearly indicated by the interest that others take to her and the chemistry that draws Edward to her in the first place that she is quite an engaging young woman.  Is it meant to be the plight of adolescent girls to put themselves down?  Now, to be fair, I'm not done the series and I do fully plan to complete it and be fair in my judgement, but at this point my dissection of the series would be that Stephanie Meyers is creating a heroine that girls should not look up to, a girl who also puts herself in a purposefully dangerous spot for...love...at the age of 17 - again, what kind of message does this send?  She is thrown into a downward spiral depressive funk over the absence of her Edward.  Really?  Can't we have a high school girl who asserts her independence?  Is that too much to ask?
