Sorry. Medical school will break you.
Perfectly sane people can barely eek by if they have to go by their own merits and finances.
You couldn't even hack through enough credits to get a teacher's credential.
Let me tell you something about good, strong mental health. You NEEDING to be a doctor, won't solve your problems. In fact, it's just a sign you are in bigger trouble then you were before.
You rationalizing this is a big ominous billboard with neon lights.
You want to know what people are like that exhibit strong mental health? They look for a practical solution to the problem at hand. No delusions of grandeur, no compulsive behavior, and not resorting to rationalizing hail Mary passes in big, life defining choices.
You are not equipped to do this.
Don't take it personally. At one time, if you committed to it, you probably could have done it. But choices have consequences, and you can't undo them all. Nobody is saying you aren't smart enough, but you aren't smart enough.
Med school will tasks every facet of every skill you have.
-Studying. Okay, you may be smart enough for that....but...
-Time management. If you had the luxury of taking one class at a time until you got your M.D....then every one would be a doctor. But that won't work, because you would be 97 years old when you're done with school.
-Family - You got three kids on the teat. Where are you going to find time to be a dad? 12 years of non-existence won't do your kids good. Your parents are going to raise them. No matter how communal and old world cool that sounds, that's fucked. Your kids need a dad.
-Wife- She is sick and might need further attention in the near future. How in the hell do you think you are going to manage that while going through med school?
-Roof- It's your parents. As cruel as it sounds, they could flip like a switch and boot you. Or intervene on your compulsive behavior and make life hell because you won't be realistic. Not easy to study under those circumstances.
Like I said, at one time you probably had the genetic traits, the nurture and the right early developmental learning to make you smart. But you screwed up. You can't erase yourself back into med school.
The Fix:
Get out of your parents house. Get out. The only way to do this, is if you and your wife handle this on your own. Why is that important? Two reasons.
You're a depressed sap, because you can't do anything on your own. No confidence, none. You pretend that you have, but it's false. Why do I know that, because you haven't tried anything else but dream of shit that will make you fail. You are afraid of failure. So afraid it, you can't pick something that ordinary people can't fail at (only in your head). So you picked med school? WTF?
So pick something realistic. Realism isn't a guarantee. If you screw up, pick something else. Just don't half ass it. Know the difference between seeing something to an end and knowing when to quit.
You are being enabled into doom.
