Failing at college and DESPERATELY needing help!!

I was always a good student in high school, I kind of just floated through never really having to study and getting along just fine. Now that I am in college, I'm suffering terribly. I put a lot of responsibilities on my plate for my first year in college: Big 12 cheerleader, living in the dorms, full time student, and  working everyday. I was on probation the first semester and didn't do a whole lot better the second semester. I have recently (like a week ago) been diagnosed with ADD and have started on vyvanse but finals ended two days after starting on the medicine so I am still left doubtful and extremely stressed. Is there any hope of bouncing back for being that low in gpa (1.07 first semester) and not hurting my financial aid? I have always been the one in the family that succeeds and the "star" of the bunch, but that puts an enormous amount of pressure on me. I have the pressure of knowing both of my brothers did terrible their first few years and college and suffered incredibly. I don't want to be that for my parents. I want them to know that they are good parents and have good, successful children. I just don't know what to do and I can't exactly talk freely with my parents about my failures because I am such a perfectionist with myself and expect the best out of me in knowing that everyone is expecting the best out of me as well...any advice would be EXTREMELY beneficial!!

THANK YOU :)
