Going crazy

I feel like I’m going crazy. My daughter is 5 weeks old and the last few days she is extra fussy and won’t stop crying. I’m a ftm and I feel like I’m doing something wrong. I usually give her the boob and that makes her stop crying and go to sleep but that hasn’t been the case since yesterday. I feel like crying and I’m just so sleep deprived bc she’ll sleep in my arms, but as soon as I put her down she’ll wake up and start crying after like 5 minutes. Is this normal or am I doing something wrong?
