Ncindasun, I soooo
I'm married w/a 10-year old, 3 pets, and I'm primarily responsible for my elderly grandparents who live nearby. My husband works in excess of 60 hours a week. Before my week of spring break this past week I very nearly had a meltdown.
You've gotten some great ideas in these posts ... time to sit down as a family and divide and conquer the tasks that are absolutely necessary. And yes, I know, that can be a long list.
After a year of being back in school, here's what I've learned ... I've had to stop pretending that I can go back to school without it affecting anyone else in the family. Like it or not, we're all in this together. Having responsibilities does not make me a lousy mom. Like you, I started this semester of clinicals waiting until after 7:00pm to go to the hospital to get my assignment for the next day (because that's when my husband gets home on Monday nights), then trying to come home and still do the SuperMom-getting-the-kid-to-bed routine while preparing - I was up until 1 - 1:30am, and then getting up at 0500 for clinicals. I've now made arrangements for my daughter to stay with a neighbor for 2 hours on Mondays, and I now have a decent chance of getting more than 4 hours of sleep before clinicals. This is a major accomplishment!
You have to pick your battles - my house tends to be a wreck too. But a change in perspective can make all the difference in the world.
Best of luck to you! Hang in there and it can get better - feel free to vent when you need to!
Edited to add: I started to wise up when my dad said to me, in one of his greatest Dad-isms ... "Dear, you're burning the candle at 3 ends ... and it's only got 2 ends!"
