Reality check for non-traditional student

You asked almost the same question in June, 2015 http://talk.collegeconfidential.com/what-my-chances/1786299-reality-check.html#latest
Have you done anything between then and now that would get you closer to your goal of becoming a doctor? Have you worked in any medical field? shadowed doctors? volunteered in the medical arena? taken any classes? etc. Is medical school a path you are absolutely devoted to or an idea that pops into your head every few years?
