To work, or not to work

So here I am in my 3rd week of the new job and I'm not so sure about it.

Don't get me wrong, I actually like the job itself. I like the work, the environment, the boss and the co-worker. 

What I don't like is my house going to pot, not seeing my kids until bedtime, and the agonizing pain in my feet and ankles. I seriously can barely walk after my 6 hour shift. I bought expensive shoes that were supposed to be awesome, but if anything they hurt more than flats and sneakers.

My dear husband is trying, but the house, when combined with 3 kids, a teenager, 2 kittens and a dog, is a huge task to keep up with. I was never able to keep up on it completely when I wasn't working. I'm putting a lot more stress on him than I think is fair.

I miss being with my family. My kids are growing fast and I feel like I'm losing precious time. I have forever to go back to work, but only a few years left with my little ones.

So now I'm thinking, do I let it go now or do I try to milk it for whatever money I can, maybe even trying to work up through the end of the school year? And if I do, what about my poor feet?

Does leaving for these reasons make me a failure and a quitter?
