Feeding nonstop

I’m a FTM to a 1 week old and have been really struggling to make breastfeeding work. First her latch was really painful and I was wincing every time I’d try to feed. This has mostly gone away but still happens at night or the early mornings where I’m exhausted. My nipples also feel like a weird freezing pain randomly. We had to supplement with formula twice so far but I want to avoid it because it made her have less dirty diapers and I don’t want to deal with tummy issues. Since yesterday, she has wanted to feed constantly. We got 1 three hour stretch of her sleeping but besides that it’s been multiple feeds every single hour. I wait for the cues before feeding and move her arm in circles until she’s limp. I also wait until she isn’t still sucking when I try to pull my breast away. Somehow, she ends up still hungry after 10-20 mins. I’m so exhausted and am trying to pump but I don’t have much coming out when I try . Right now she’s been feeding on and off for three hours and now she’s wide awake. She also will jab her head at my nipple and seem super frustrated until I help put it in her mouth. Is this normal? I know about cluster feeding but I’m worried this is more than that. She barely goes an hour between these feeds and I’m terrified of tonight because she hasn’t stopped feeding now and doesn’t seem to plan on it. My back, shoulders, and nipples hurt. Please help 😭
