My advice? Bite the bullet and do the accelerated BSN.
That's what I did in your situation. I was so discouraged in my career as an attorney, I always felt something was missing. Once I found nursing, my life and outlook has changed dramatically for the positive. I love being a nurse and working as one. Bedside nursing is very different from drafting complaints and litigating in court, but I don't regret a second. I debated for a while doing ADN or LPN or ABSN and ultimately chose to get it over with and I figured I would have better chances to get a job with the highest degree. I got a job right after graduation, and this is in the NYC metro area, which is one of the toughest job markets for new grads. One year in an ABSN will go by VERY quickly, trust me, and to know you will be in the job market faster is a plus. You're a lawyer, you know what networking is about, it's no different in nursing. That's the key to getting work in nursing these days, it's about who you know and who knows you --- standing out in clinicals and being kind to everyone you meet, and that means CNAs and staff you meet along the way, not just RNs. My unit has 2 former lawyers, me and another nurse, I think that's unprecedented anywhere right now in one medical unit. Having that law degree is nothing but an asset. It's not a guaranteed ticket to a job, but it shows employers off the bat that you are groomed in professionalism and have life experience that makes you a better nurse.
I agree, $60K is a tad expensive for an accelerated BSN, but if you have no other options, I would do it in your situation. Taking the longer road of LPN or ADN would be in some respects too slow for where you want to be (and less income earned along the way). Is there a state univ ABSN in your state you could possibly attend instead, even if that means being away from your family for a year? I know many parents that have done this as the sole breadwinner of the family. It can be done.
My law degree and experience will not be a total waste, as I plan to use it to my advantage later on in some way. Merging my law and nursing career is something I want to do eventually, not sure how though. But for now, I am happy to invest at least 5 years at the bedside just to learn the nursing craft.
Good luck, I look forward to seeing more lawyers enter the nursing profession (as long as nursing is their true calling).
