Padme Lives!
Psych...made you look...
Anyway:
You see...there was no physcial reason that she should die. She wasn't choked to death...she wasn't thrown against a wall (as in the initial script), and she wasn't hemorraging from childbirth. Yoda put her into a death-like state...that way Anakin/Vader would not seek to find her or the babies. If she had indeed "lost the will to live", don't you think Obi or Yoda could have used compassionate mind control to show her that it's better to stay alive for her children than to die because her husband was a dink!
So...Yoda puts her in a death trance...they have a huge funeral to make it look good. Later, Bail Organa and his men remove her from her tomb/crypt and take her to Alderaan. She gets to have some time with Leia (which better explains the fact that Leia remembers her real mother) but leaves to work the rebellion underground...this way, she (her character) can be used in the new TV series. 😮
Okay...far-fetched, but it makes more sense than she died because she didn't feel like living.
