First time mum

My baby is currently 10 weeks old. Things has been really challenging since my husband has a very demanding job and I do not have any additional support of either side of family member. Each time my baby fuss and refused to settle (especially when he cannot sleep) I find myself crying more and more often. With the recent covid situation, I dare not step out of the house which causes my mood to get worse. I guess my question is, when will things gets better or easier? 😪
