First things first. Take a nice hot bath and just let go of the past couple weeks. Talk to your husband and mom about setting up comforting routines for feedings. They should be different than the ones you've created, but incorporate the same elements: songs, pleasant talking and encouragement, fluffy blankets, a nice soothing place to sit. Then, in a few days time, try again. Leave the house for several hours. See if your mom and husband can be there together, so that they can use each other to take breaks if they need to.
When baby becomes hungry, have them try, gently and without pressure or expectation, to give her the bottle. If she refuses, immediately stop and go do something else. If baby enjoys being bounced, sung to, tickled, bathed or taken for a walk, then have them do that. A little while later, casually try again. Make it fun and pleasant. They should be confidant and relaxed. Again, no pressure or expectation. If she takes it Great. If not, that's okay too. There is a difference between a hungry baby, a really hungry baby and a starving baby. When she is hungry, she will be cranky but when she is really hungry she will be more likely to take the bottle. She will not starve.
If she doesn't get enough milk during the day, she will make up for it at night. There are ways to work through that. I chose to co sleep because then I could stay in bed while nursing my child. I slept through the feedings and woke up rested. If that's not an option for you, you could try putting her crib, bassinet or co-sleeper in your room, so that she has a separate space but is still near by you so that you don't have to interrupt your sleep only to have to work in the morning.
If she still rejects the bottle, after a few sessions like this, certainly try different nipples/bottles.
If she really never takes a bottle you can dropper feed or spoon feed sometimes.
Good luck, you guys will be able to make this work. Bottle rejection is totally normal and is just a sign of a baby who knows what she wants.
