After successfully throwing my deeply troubled 20 y.o. daughter out my husband suggested she return home after 5 yrs. away to finish her social work degree.(she takes 2 classes @ a time and still gets C's & D's. She's been a solid AA follower, nice person (in gen'l), works p.t., not good student with little or no genuine ambition to take her life seriously. By this I mean, to finish school well so that she can get into a grad school or land a career opportunity after graduation. My 21 y.o. is a senior in college & wants medication school. The other daughter. just got into Columbia U. grad school. But this one is still operating at a teenage level!!! I can't stand having her around anymore. She is just not making it in the real world...What to do, what to do?
