Oh dear, big deep breaths hun. You do sound very stressed indeed. Definitely do not stop feeding her
By all means try to encourage her to take the bottle but don't insist too hard, you don't want to put her off. For now, just go with the flow, you might find she improves her DF with BFing, and if she doesn't, something else will work out. Lots of babies don't DF at all, some parents prefer it that way and some babies just don't 'get it'.
If it's any consolation to you, I did DF with a bottle of EBM for my LO1 until he was about 5 mo and then decided it was too much hassle. Best decision I ever made, no more pumping! And we went on to BF the DF for a few months after that. LO2 flat out refused to ever take a bottle and DF too. I would focus on the DF not the bottle, if I were you, and also try to accept that you can't *make* her do anything (not one thing, it's a good lesson to learn early on
). If she won't DF, then she won't.
Big hugs, don't stress, it'll be fine.
