Since you've made it this far, you might want to just slowly transition to a sippy cup. You'd be surprised how smart babies are... I'm sure she could figure it out if you keep trying. They make sippy cups with very soft nipple like tops.
If in fact you do want to use a bottle.. my best suggestion is to have a supportive and very patient (usually a female) watch the baby for a couple of hours (right during a feeding time) and you, (mommy) go out for awhile. Go shopping, get your hair done, etc.
Your baby will not go hungry. She will eat when she is hungry enough... but you have to let her get to that stage. The person watching her should try every 15 minutes or so. Keep giving her the bottle and try. This will eventually work... but you really have to be away. If she sees you, she will refuse the bottle because she knows you're right there.
Be aware - once a baby converts to a bottle, they often prefer the bottle... then nursing actually becomes more difficult... because they only want a bottle.
Good luck!
