failing

I feel like I'm failing. They gave the baby bottles in the hospital. With my permission, due to her blood sugars being crazy low (at one point 15). But I want to breast feed so bad. She's doing better now (she's barely 86 hours old), we are home. I always put her to breast at the hospital then supplemented with formula. But she has now started to pull away completely from the breast and always wants the bottle. Any ideas?
