Tired!!

My boy is now 4 weeks old and I am so overwhelmed!! I understand newborns cry but I feel like my lo cries just to cry! I can feed him,hold him,rock him,change him etc and he will still cry!! (For hours!) it makes me very emotional to the point where we are both crying! He really makes me feel like I’m doing something wrong!! & it really sucks because I have zero help! My husband leaves to work at 1am & doesn’t get home until 7pm. He’s tired already and I know how much he needs to sleep so I don’t bother asking. I’m also in a whole different state with no friends or family. So this is definitely hard on me.
