In need of encouragement !? 😓

I can't help but think I wanna stop breast feeding sometimes!! I'm tired of the leaking beasts, only being able to wear two bras over and over, having to pump, and the back ache I get most days. If that wasn't enough, my little ones always fussy as if in pain now. This past week has been the worst she's been where she CRIES (loudly) while feeding, farting, and pooping. I've tried giving her gripe water and not even that seems to work. I've had a feeling it might be the dairy? Every day I tell myself I'm going to eliminate dairy from my diet and I do it one day and then end up caving the next (not always on purpose) and then feel like a horrible mother once I see her cry!! Idk what to do .. I'm strongly considering trying out soy formula ? I don't wanna give up breastfeeding her just yet because I know that's what "is best". Just don't know if I can keep up with a dairy free diet!! 😪
