I gave up a lot of sleep and weekends. I also gave up my excuses. Make it happen. You can do it.
The longer you wait....the more unfamiliar and distant the information is going to become. The old saying, "If you don't use it, you lose it" stays true.
Wanted to add: You have the strength to get up every day and go to work, take care of 2 kids (one being a toddler), you take care of your family and you passed nursing school.....no reason why you can't pass the NCLEX....you are a strong woman/mother and soon to be nurse. Finish what you started 2 years ago and don't let anyone get in your way...not even yourself.
