3rd baby, cant keep up with my kids

I'm pregnant with my third currently 26 weeks, and my energy is dramatically dropping. I have a 3 year old and a 1 year old, INTO EVERYTHING! They drain me to say the least, I'm having a hard time imagining having another one around. I admit now had them way to close together in age! Does anyone feel like what the hell did I get myself into, I cant barely breathe most days between being pregnant, caring for them and working. I dont do day care for my kids, so me and my husband work off days to care for them, just feel like there is never a break! Any moms find comfort in a daily routine to find a break or maybe eating something to keep you going while being pregnant and running ragged? Lacking something or losing my mind for sure haha
