What do I do after college if no insurance?

Some options... You can stay on your parents insurance plan up to age 26. You can also apply in the private insurance market (if you are healthy with no preexisting conditions, shouldn't be too expensive). If you need just basic primary care, try to find a federally qualified health center - these are clinics that charge on a "sliding-scale" which can be a great bargain for people not earning that much.
