I'm seriously depressed or pretty close to it. how do i stop crying?

its the last day of school here at LSU, im not making the gpa needed to stay on my scholarship so now my only choice is community college. it hit me hard, i guess the disappointment of not making it in college. every time i think of it i cry im cryin as i do things on my computer. can anyone give me some efficient ways to not cry i have a headache but the main reason is i dont wanna cry when my parents come to pick me up i move out of my dorm to drive back home for the summer. anything helps plz
