How do y’all do it?

First time mom & I have an almost 6 month old. I was able to take the full 12 weeks of maternity leave & I’m grateful for that, but y’all.. I do not enjoy my job whatsoever anymore. All I do is wish I were home with my little guy. I already didn’t enjoy my job prior.. now it’s just worse. I’m literally exhausted every single day. I want to have the energy to care for him & do my job in the best way & I try but I just feel I literally never have any energy. He has started waking up at night again & then I really don’t want to go to work the next day. It’s so hard for me... how do y’all do it? 😭
