Newborn phase

Please give me tips, I am desperate atp. My baby is so fussy, I can’t even put her down for more than 10 mins. She’s a completely different baby from my first and I don’t know what to do, it’s like I forgot everything about the newborn phase.. I’m so ashamed to admit that I even forgot about burping, idk why but my mind went blank when she got here. I’m so overwhelmed, she barely sleeps which means I don’t sleep. I have to basically stay awake around the clock because she won’t allow me to put her down, is this just apart of the newborn phase? It’s so depressing 😩 Also both babies were breastfed, with my first she wouldn’t poop everyday but when she did it was a lot which doctors said was normal but with my second baby, she literally poops so often! I’ve changed 7 💩 diapers in 3 hrs before. Is this normal?
