First of all…state schools do not require that you come in with a major and never change your mind. That’s false.
I am the one who wrote about the student I know who graduated from a top 20 school and spent a year working at Starbucks following graduation. It’s not uncommon…most find their way, get counseling if needed, and figure out what they want to do. My dentist’s daughter spent 2 years traveling before heading off to medical school (obviously she was able to afford to do this).
There is nothing wrong with doing something for 2 years (consulting, teaching abroad, etc) and then moving on. Again…happens all the time.
Please focus on today and getting your family into a healthy state. That is the only way your D’s life (and yours) will fall into place.
