What can it be??

My 5 week old baby just recently started not sleeping at all 😭 I’m so sleep deprived night time is the worst!!! & during the day she does not nap for more than 30 mins .... I feel like I’ve tried it all , i swaddle her , un swaddle her, feed her changed her diaper play music talk to her literally everything idk what else to do I’ve tried it all ... some days she’s just up not making a sound & other days she’s inconsolable ... super fussy & just non stop crying !! Also just recently she’s been wanting to be held all day/night she wasn’t like this at all now the moment I put her down its game over lol how do I make it stop 😭 she’s non stop crying if I don’t carry her
