Advice ?

I gave birth to our second child on the seventh , just last Friday . And am having a very hard time adjusting to being a mommy of 2 . Our daughter is 3 years old & is having just as hard of a time adjusting as I am . my husband works away so I am basically alone . I wind up crying myself to sleep most nights out of frustration and anxiety . I guess I just would like to know how you other mommies adjusted to going from a mommy of one to a mommy of two . I'm really struggling here 😕
