So annoyed

Im loosing patience and hope. my baby refuses to take a bottle from anyone, ive tried cheap brand bottles, playtex, silicone, Nuk, Avent, dr browns, munchkin latch...I regret breastfeeding....im going back to work soon is she going to starve herself because my breast will not always be there to soothe and feed her

I know everybody raves about how good breastfeeding is but how must I go back to work, so all the expressed milk ive been storing is going to go to waste Aaaaaaaarggghhhhhhhhhhh I wanna scream
