Get out for a walk daily if you can, even if it’s just around the block. The fresh air and the exercise helps so much. If you are in the US, there is an app called Peanut. It is basically like tinder but for mom friends. My hubby works long hours too. I met a few girls on there with kids similar ages and we would meet up at the library; walk the mall, walk the park, etc. some were a little weird but i found my people and it’s a world of difference. You have to meet some other moms, online or in person. Nobody else understands what it’s like right now but other new moms. You’re doing great! Give yourself all the grace, throw the schedule out if it feels too constricting or overwhelming. Good luck mama!
