Yes. I am in the same situation. I am a also woman with a husband and three children.
However, you will be undergoing a medical education only one ( if you get in, that is ) and can have a great bearing on your future. Hence, I am tempted to go out of state if I get into a prestigious medical school that is far off on the other end of the coast.
Make sure your motivation doesn't fail, because I'm driven crazy by what I'm trying to do and I can't live with myself if I don't get in somewhere good, which is a good thing because that's why I'm at where I am now. Don't worry about what your parents or your family thinks. You live once, so go do it.
Good luck, bro.
