Yes, if she moved away in June, then that is under 6 months.
In regard to support; support covers everything. It is not just food, clothing, education, and a roof over someone's head. It is the amount spend on movies once a week, the $50 you spend buying candy at the mall, getting your shoes repaired, etc. It is every penny spent. While you are probably looking at big-ticket items, if she spend $30,000 on her own support, she spent over half if you spent $29,999.
