are there any other Caregiver/CNA/RN mamas on here?! How do you do it? care for others all day long then come home and care for your family? and on top of that..be pregnant all while doing so!? I constantly feel drained and burnt out on working because I long so badly to be able to fully care for my family. I feel guilty when I spend my evenings with other people's children, doing for them what I would my own child and even more sometimes, and then coming home without enough energy to do that same with my own family! Does this ever go away?
