Hi L.,
Kudos for breastfeeding!
I know you are worried and this is stressful. I encourage you to call her pediatrician if she has no visible symptoms in her mouth. It sounds like she's in pain for some reason. Could she have thrush? It looks like white curds on her tongue (and you might have shooting pains, too) which don't wipe off. The cure is to paint with gentian vilolet on a cotton swab. You must treat her mouth and your nipple, I believe twice a day. It is very messy and it does stain, so be warned. But it works quite well.
Might she have blisters in her mouth? If so, do take her to her pedi and get it checked out. If this behavior does not change within 24 hours certainly have her checked out and make sure she has no throat infection or something. IT takes so much more work to get milk from the breast than the bottle that if it hurts her she will obviously opt for the easier path.
Do keep her close to you while you bottle feed, skin to skin, to keep your milk supply up and keep her feeling safe.
I hope she feels better soon.
