It is sad when we have to give up breastfeeding before we're ready. That being said, it may not be too late to get the latch back.
When you are bottle feeding start with your daughter close in, cuddled against your bared breast. And bottle feed her so she does not get upset. Reacquaint her with the feel of 'skin to skin' contact during feeding. Switch the breast she is cuddled against, just as you would with actual nursing.
After a few days of doing this, feed the first ounce or two from the bottle, so she isn't so hungry. Take her off the bottle and burp her and then offer the breast. If she balks, feed a few more ounces and try again. Gentle persistence is the key. Gently enough that neither one of you needs to get upset, but consistently enough that you both may end up where you want to be.
There is debate on which nipple texture, shape, flow, etc. is best to reduce nipple confusion, so take what you read as guideline and go with your instincts as you know your daughter best.
In the end, you're absolutely right, though. Feeding doesn't need to be traumatic for either one of you. You are still feeding breastmilk, which is the best thing to give your daughter and bonding can still take place with a bottle if latching at the breast proves too stressful for all involved.
Good luck to you both and I wish you success in re-establishing the latch.
