L.N.
I would go back. I quit a year ago and I am already feeling like you are. I quit last year because I didn't find a good pre-k for kids, and the public one was out of question. Now they're in kindergarten and I find myself either cooking or cleaning.
My mom was a full time lawyer with 3 kids. We're all happy well-adjusted adults. She was a better mom because she did her thing, and when she came home she was a mom.
I am thinking if I find something good I will go back to work too.
Good luck,
