Baby cry’s

I’m 4 weeks pp and all she does is cry when she’s awake.. I get so frustrated and just cry I don’t even want to pick her up sometimes and I hate that I had to get to that point.. I’m ebf which has gotten so much better but it’s as if she’s not getting enough and I’m producing a lot.. shes was on the breast for about 20 minutes each but lately she has been taking herself off around 10 minutes and she burps while feeding so I take that as she’s full.. every time someone comes visit (just my mom sister and mil) they are always like “she’s hungry” and I literally just had fed her.. I can feed her more and she pukes.. to put her to sleep I have to constantly put the pacifier back in her mouth (she doesn’t have nipple confusion) idk what to do. I feed on demand but she cry’s the entire time she is awake she never just sits and chill and look around the room or interact with me and it’s becoming really depressing..
