Anyone else with an extremely difficult baby?

E

My 4-month-old baby cries all the time - basically since she was born. She is just so fussy and unhappy. Family and friends are so eager to look after my son but not even my mom wants to help me with this baby. My anxiety is through the roof because of the constant crying.

Anyone else?

And anyone with older kids who were once difficult babies - what are they like now? Am I doomed for life?
