Am i still dealing with postpartum ?

So my daughter is 5 months old… i been stressing out, sleepless, tired, crying because shes growing up , crying because i miss being pregnant and my belly bump…😰 and im angry because she hasnt slept through the whole night yet😫 im just sad… stressed overwhelmed depressed… idk what to feel … i want her right by my side but i have to go back to work💔 so im really more depressed i feel like my heart detached from my body… i always cry though because of how shes growing up and miss being pregnant still sometimes i feel like shes still in my belly
