Trouble latching 😭

Baby and I are both having a pretty difficult time getting the hang of latching. We are 3 days post partum. I had to get a c-section so I'm still extremely sore. She's lost a bit of weight before coming home. I know it's normal but they were slightly concerned. Any mommas out there on the same boat as me? Or figured something out? My milk is just starting to come in but I still feel like she's just not getting enough food and it's extremely depressing for this first time mom. So any advice would be greatly appreciated.
