WHOA!!! $35K for an LPN diploma/certificate?? My entire certificate including transportation and child care cost under $12K. That kind of money will pay for and RN degree.
Now, personally, I would say stay where you are. No stress, more pay than an LPN. Many LPN's start out as casuals. Depending on where you live permanent positions are obtained by seniority. Do you want to work nights, evenings, two weekends out of four? Be low person on the vacation list? That's the reality of starting out as an LPN in your 40's. All day shift office hours are rare, competition for them hard, and most require a years experience.
The four semesters of LPN school are hard work. Quiz after quiz, leading up until finals, clinicals and care plans
, they all make for late nights. Be up before the crack of dawn to get to the hospital for clinicals (nothing like starting your car in the dead of winter to get to clinicals and find a parking spot with plug in?) Dealing with the little cliques that always form in classes that are mainly female. Do you really want to do this? I'm a realist. It was one of the most stressful years of my life (we did all four semesters back to back and graduated in 13 months).
You really need to sit down and discuss this with your entire family, because it will affect all of them. You might want to try volunteering in some healthcare type agency, if you want to think more about it.
