On the edge

Oh my lord I am on the verge of a breakdown. I took her alone on a 6 hr flight to see my family and I don’t know if I’m gonna survive this trip. She’s been hanging on me for days my arms and back are killing me. The house isn’t fully baby proof so I have to constantly follow her. She is so off her schedule, won’t nap, hardly eats, our time zones are off, I’ve barely slept and I feel like I’m gonna drop dead. And at the end of it I have to take her on the return flight... I don’t know what to do.
