Looking for some support

My little one has a lip tie and doesn’t latch well. I’ve been pumping but not nearly enough to keep up with her eating. I am 6 days postpartum (I get about .5oz each pump, she eats 1.5 oz each feeding) I am having a really hard time accepting that we have to supplement with formula. I really wanted to breast feed. I feel like there is such a negative stigma around formula feeding, does anyone have any positive formula feeding support they can provide? I see lactation on Tuesday, but I’m trying to mentally prepare for my worst case scenario.
