Rough start in first year of college?

im 18 years old and i am almost done with my first year of college. my major was biomedical science and it was not easy for me at all. I finished my first semester with a GPA of a 2.2 and now I am very scared about my grades this semester since I already dropped one cl and one of my other grades in a cl was a C. I changed my major for next semester to kinesiology, so there are not as many challenging cles but since my GPA is not that good and is at risk of being dropped even lower, I know that my athletics and my chances of transferring to a different university is at risk as well. I was always a good student in high school and I did not become a party animal my first year of college. This past semester I think that my adviser put too much on me since I had to take Biology II with lab, Chemistry I with lab, Trigonometry, and English II. im not going to lie i got lazy at times but I always put forth my best a majority of the time and I still struggled in some cles. so im asking if i still have a chance of bringing my GPA up before I lose everything. and if I do have to leave school because of my GPA what I should do next and if anyone has past experiences like this, but turned it around.
