How do you balance working (away from home) full-time while still having time for your kids, significant other and yourself?

For context I’ve been a SAHM for just about 2 years. I tried the whole daycare thing in the fall and during that time I worked very part time. Daycare didn’t work out so I returned back home after about a month (daughter was adjusting fine - the daycare itself sucked). During that time of even working part time I felt like it was a lot to manage.

My husband and I want to move (we are outgrowing our home) as our 5 year plan has turned into 10. But this would require me to return to work full time and daughter would also need to be in daycare full time. I truly can’t wrap my head around how working full time moms keep their head above water. Just the thought alone is stressing me out.

How do you do it? How are you ACTUALLY doing mentally/emotionally?
