Baby screaming sends me into a rage!!!!

My baby girl is 6 weeks old and is very hard at times! Yesterday she was fine all day!! Very content and settled! Today she just won’t stop! She’s been crying and squirming all day! I think she has trapped wind and iv been trying everything to help! But I’m losing my shit!! I also have a 2 year old that has been playing up today because unfortunately I can’t give her any attention with my baby screaming her head off! I’m getting so angry I start screaming and throwing stuff! Im crying my eyes out and I just don’t know what to do! I wanna just smash something up! Or just leave the house! 😡😡
