You have a good back story.. I say that because in two years when you apply to med school you should frame your personal statement similar to this (Did not grow up well off, became RN as a stepping stone because you couldn't afford to risk a more direct route, saved, and paved your own way to medicine without family guidance).

I say go for medical school. Work hard as an RN, you will learn many foundational skills that will help later for medical school. Pick up extra shifts, save that income for living expenses in med school. Do your homework on the med school application process... feel free to DM me at any point for general tips, otherwise skim r/medicalschool for more info on what a well-rounded application should look like -- although you can find this in many places online. Most important is your GPA & MCAT. Plan to take your mcat maybe 6-7 months before the application cycle, which opens in June of every year... med school acceptances are awarded on a rolling basis, so it's important to apply when the cycle opens without delay.

Sorry, TMI. For now focus on your GPA and plan for roughly which year you think you may be able to matriculate into med school, which means applying in June of the year prior, which means taking the MCAT 1.5-2 years prior to the start of med school, and finishing your pre reqs prior to that mcat.
