3 years in college and still have no idea what do i want. it's depressing. please help.

@pasta82 it’s 2015. i graduated in 2012 so i was a senior in 2011-2012. so i was in high school 3-4 years ago. and i am still in my third year in college. my GPA (without this semester) is about 2.7 out of 5. i already started taking the classes i failed at. i was suppose to major this semester but since i failed a lot of subjects i couldn’t. and i will most likely have to take some classes during summer break
