Baby won’t eat

My baby’s 3 months, she’s about to turn 4 in a week or so, It’s been the worst month of my life, I was exclusively breastfeeding so she doesn’t like the bottle very much. My problem here is that a few days ago (two weeks or so) she started hating the boob, only takes it while sleeping so when she’s awake I have to fight her so she can at least take the bottle, I’ve been having mental breakdowns and crying every day because I don’t even know how to help her, I don’t want her to get dehydrated, I read about a baby who died because the mom didn’t know if the baby was getting colostrum or not, so the baby died of dehydration at 14 days after birth.

I don’t know what’s going on with her because she eats while sleeping, so when I get her to sleep I have to put her on her crib and then go quietly grab her and make her eat, so hey I AM DYING I have little to no time for myself. I don’t think I can’t do this anymore please help! I’m first time mom and my family live really far from me😭
