Mom needs space

Nicholeen, Im a home school mom of 3 ages 4.5, 3 & 1.5. lately I have felt a strong need to have my own space to breathe. We currently live in a 1350 sqft home. We are about to make an offer on a home that is 2500 sqft which fits most of our needs and is in our budget but it does not allow me for personal space. I am also asking myself if the space I need isn't exactly physical, but emotional & spiritual. It feels like I can't breathe, relax or enjoy myself. Am I just self focused right now? Any insight to what might be going on? I do wake up early to have devotional time and go to the gym for 30 mins before the kids go to bed. I also have good friends, church & support. Have you ever experienced this? Thanks for some direction!
