(((((Rap)))))) it's a long drive, and you're doing it by yourself. There's only so much one person can do in one trip! That doesn't make you worthless and incompetent at all, it makes you a normal human being.
You did the best you could and there is nothing to be gained by looking back and wishing you'd done it differently. What's done is done, and you accomplished your goal, right? You got the family moved. That's a positive thing too.
Hang in there, gf.
