Oh dear. It's nice to feel wanted but I know it's really frustrated to feel tied down. My LO also went from taking the bottle totally fine for about a month and then one day she just rejected it totally. This is the advice I was given by many sources:
1) try a different bottle
2) keep perservering - babies won't starve themselves (this one is hard, especially if you find it difficult to hear them cry)
3) forget the bottle and offer milk in a beaker or cup (a 'doidy cup' is especially recommended)
4) keep breastfeeding and wait until she drops her feeds when weaning (obviously a way off for you)
5) keep offering the bottle but don't force the issue
Obviously you could try a combination of all/none of these...not sure what you've already tried (haven't read your other post).
We opted for the cup and wait for weaning approach as it's not super important for us that she takes a bottle. My friend on the other hand whose DD is 4.5mo has recently opted for the stick it out approach and it worked for her - her LO just stopped fighting it one feed and started taking the bottle.
HTH in some way. Fingers crossed that whatever you try works.
Not sure if you'll check this thread so will post in your bottle feeding thread too.
Good luck and let me know how it goes.
Natasha.
