OP, I'm going to present to you a perspective that you haven't really seen before on here.
You have to know why you actually want this. Do you have a real reason, or is it just something you
think you want because of society glamorizing and sensationalizing it? For most, it's the latter and they aren't even aware of it. Based on your comments in this thread, it's unlikely you're different. You aren't actually in love with being a doctor, you're simply in love with the
image of it. If being doctor truly was your passion, you would have started on it before getting married and having kids. Chances are you're only
convincing yourself that this is your passion, rather than it really being one.
Let's go further.
Why are you here? Do you like helping people? Is medicine simply interesting to you? Are you in it for the money? What if this is just a midlife crisis? Are you lying to yourself when you answer these? Most people would be, since they aren't aware of their subconscious influence. Allow me to disillusion you:
"Do you like helping people?"
- Most people who claim to like helping others don't ACTUALLY like helping others, they simply like feeling as if they are a good person, i.e. making themselves feel better. In other words, ego. It isn't about doing what is right, it's about the status associated with it. They don't care for others out of genuine altruism, they do so to virtue signal to themselves in order to feel a sense of moral superiority. People who truly like helping others don't ever say "I like helping others", they simply don't verbalize it that way because they don't feel satisfaction from helping others, they feel satisfaction from seeing people recover and improve themselves and their lives after what happened to them, whatever that may be, and seeing the joy and happiness they get from finally getting said situation fixed.
"Is medicine simply interesting to you?"
- If this is the case, then going into medicine will most definitely ruin that for you. You don't make your passion your job unless you're prepared for it to become one. That means that medical school will grind out all love for science that you have because of how hard it is and how much effort you need to put in. Sleepless nights, caffeine pills, hunched over for hours on end, etc. and all so that you can learn things that you will never ever use as a doctor (yes, you heard that right; most of what you learn in medical school isn't actually used by practicing doctors).
"Are you in it for the money?"
- If this is the case, then it's not worth it. Not because "you shouldn't do it for the money, you should do it because you love it!" type garbage, but because, you won't get to enjoy the wealth you do create, especially at your age.
What if this is just a midlife crisis?
- It is, unfortunately. Textbook case, even if you don't really feel it.

You're 38, married, and have 2 kids. Bad logistics. Let's say you do follow through though—what's the prognosis going to look like? Let's break it down:
- You'll be 39 by the time you first enter med school (considering you didn't finish all your classes yet). 4 years of med school = 43 when you graduate and $500,000 in debt. After is 3 years of residency, where you work ~80 hrs/wk at ages 44–47, while making only 45k a year. Less than an Uber driver. By the time you are finally "free", you will be ~47 years old. Don't forget about the debt. You'll probably be in your 60s by the time that is paid off, unless you want to continue working mad hours and not see your family for another several years. This doesn't even consider that you will likely want to move to a nicer house, which will only enslave you to debt even more. Unless of course, you don't move, in which case all your hard work would literally be for nothing but a title...
- Like others have vaguely described, your family will be strained. But how strained? Well as it currently stands, over 50% of marriages in the US fail. You are already more likely to get divorced than not, but by being absent for a minimum of 7 years and a maximum of ∞, I can guarantee you that your chances are much higher than the national average. Your family will be split and your kids destroyed. If you are in school or residency when this happens, the mental strife may cause you to fail out. The judge is going to side with your spouse over you because you are so busy so you will have no custody of your kids and might not ever see them ever again. If/once you are finally practicing and are starting to make good money, well then you now have to pay half your income in spousal support and child support for arguably the rest of your life. All your hard work and your wife takes half of the money you earned, while he/she ****s other people. You still don't see your kids, and have debt to pay. Would you regret your decision at this point?
In the end, it's just another job. Medicine is a business more than it is a service. If you don't become one, so what? Nothing really happens. Is it really being a doctor that would make you happy? Or is there some underlying psychological phenomenon that's causing you to see being a doctor as making you happy? My assessment is that it's the latter.
