So -- you only get so many evolutions around the sun on this spinning blue ball --- you have to do what YOU want with your life -- no regrets --- I can tell you from experience, entering/not entering a career because of "family restrictions" is NOT living --
People have this fantasy of what it's like to be a doctor and it's not all burritos and strippers, my friend -- it's a LOT of hard work and dealing with people at their worst with huge amounts of debt and a lifestyle that consumes you, easily. DO NOT do this because of pressure from anyone else, period. I've have seen way, way too many parents when my children were little who tried to get a second chance on life through their children -- and I'm talking about grown men getting worked up on the sideline during a 7-9 y/o soccer game. You would think it was a World Cup game -- really? One thing I have always told my children -- don't do this because I'm doing it, do it because it's what YOU want -- and I also tell them this --- pick a career that plays to your strengths, one you enjoy and one where you are not ever at the mercy of some corporate bean counter who decides that you're on the next layoff list (phrase I use is "don't ever be in a position where some corporate bean counter determines whether or not your family can eat."). Barring that, go for it -- don't get stupid and get a degree in 18th Century early American art history where you'll most likely learn the phrase, "Would you like fries with that?". If you have a chance to seize more control over your own future, grab it with both hands ---
It would be better to withdraw now, keep a failure off your record. That way, if you change your mind later on, you have a chance to get back in -- otherwise, if you flunk out, you've pretty much shut that door and maybe others (like law school) ---
Up to you but do this one for yourself -- be the adult.
