Postpartum, 3 months

So I am currently 3months PP and I am starting to feel very down and have way less energy. I do have a new job as a school nurse and I work 40 hours a week but that was the case while I was pregnant too but I never felt like this. My poor spouse is so full of energy and wants to indulge in sexual activities way more than me. I just really don’t have the energy from the baby, and work, and being social all the time I come home so exhausted. I guess I am looking for any tips and or products to help with my energy level or libido??? (I am burnt out of coffee) 😭😭 help
