SAHM here, question for other SAHP.

So I'm a stay at home mom and we do a home base school thing with the kiddo, so we're together 24/7. And that's ok. I chose this, no biggie. But my question to other stay at home parents is, do you feel useless when the kid (or kids) is/are gone for an extended period of time? Like my kid went to his grandparents for 2 weeks for Thanksgiving and he'll be home in a few days, but I just feel super useless and kind of sad. The first couple days are nice, but after a while the quiet is too quiet. Anyways, can anyone relate or is it just me and I have weird co-dependency issues? LOL
