be run ragged
To be utterly exhausted from long, tedious work or having too many things to do. I've been run ragged trying to clean and organize the house before your mom comes to visit. I love this work—you're run ragged at the end of the day, but you feel like you've done something truly productive.
run someone ragged
Fig. to keep someone or something very busy. This busy season is running us all ragged at the store. What a busy day. I ran myself ragged.
