To me this is a song about failed (or failing) marriage and depression. She's feeling smothered, he's always around and she has no time for herself or her dreams. She maybe feels guilty that the relationship is ending ('to have and to hold'). The 'blindness offered to appease' is her going along with it all cos it's easier for her. And finally, she can't take it anymore; she has to leave, mostly because she had no business being in the relationship to begin with ('the state I'm in...') because of her condition.
