re: Mid-life crisis reality check

Really sorry to hear. I would encourage to seek any avenues to put yourself on a path to greater happiness. I would discourage you however, from choosing a long professional education path in your 40s. Admission is difficult as you will be competing with applicants who can provide many more years to the profession than you will be able to. The time and effort commitment is total and will be difficult for someone out of school for quite some time. Not to mention it will be a challenge to realized a return on your investment at your age.

tl:dr I encourage to you find a new path to career satisfaction but professional school is likely a poor choice for you.
