I'm sure you've heard plenty of tips before even coming here, so I am not going to bore you with study tips, etc.
My advice: TAKE CARE OF YOURSELF...and take on nursing school ONE day at a time.
I can't tell you how stressed out and overwhelmed I let myself get when I would worry about everything that had to be done within one week, let alone one month or one semester.....so I finally just started focusing on one day and one task at a time, "Okay...today I just need to go to class and study when I get home." Instead of freaking out, "I have class this morning, then I need to study, then I need to read ahead for next week, and then I have to start on my careplan for next week, then I need to write my paper that's due in two weeks, and I still have computer time that needs to be completed before the semester is over....aaaaaaahhhhh!" It is just too much to constantly worry about at one time. Make short term goals, get what needs to be done first done (ah prioritizing!), and then take time to do something non-nursing related (for fun...not the laundry)
And speaking of laundry, household duties, etc....DELEGATE! If you don't get to it, then you don't get to it. Do not feel guilty. There is only so much of you to go around. Your family will reap the benefits in the long run.
