Baby on boob all day!

Hi everyone! I’m a ftm and my baby just turned 1 month today! I’ve been kinda struggling these past few days because my baby wants to be on the boob practically all day, anytime she’s awake she just wants to be at the boob, the pacifier will hold her off just a tiny bit but I’m EXHAUSTED I haven’t eaten all day today because she just wants to be constantly held and at the boob. Is this normal? Should I be concerned ? She was 5 pounds and 13 ounces at birth and dropped to 5 pounds and 9 ounces but now she’s 7 pounds and 11 ounces as of last week, she seems to be pooping and peeing well. Is she just comfort suckling? Cluster feeding? I’m just so tired. I try to put her down for a nap while I nurse her and as soon as I put her down and walk away to quite literally use the restroom she starts freaking out! Am I doing something wrong ? I haven’t showered, brushed my teeth or done anything because she wants to be on my boob or carried. I feel like a horrible mom because I feel like I’m doing something wrong. I know when babies cry it’s because they are trying to communicate something to you, am I missing something ? Pls help 🥲
