3 week old constantly crying

I’m writing this post almost in tears because I am beyond frustrated. I have a 19 month old toddler and a 3 week old baby girl. My newborn has seriously been crying non stop since 11 am and it’s not 530pm!!!!! She does this every freaking day and I just don’t know what to do at this point. I swaddle her, feed her, change her diaper, make sure her clothes are comfortable, sing, rock her e v e r y t h i n g you can possibly think of. I’m beyond fed up. It’s making it really hard to bond with her. Is this normal for a 3 week old to do this everyday? It’s driving me nuts. I’ve given gas drops and gripe water and bought different bottles and nothing works 😭😭😭
