You won't get kicked out of college for having a bad semester. You might get put on probation for a while, and might have to retake some courses, but your life will not be destroyed for the next two decades. You are not the first person in history to have a bad semester in college.
As far as your grades go, I have never met a professor who would not make accommodations for a student who does well on a final but poorly on a midterm. If you do well on your finals and you go talk to your professors, I would be surprised if they weren't willing to give you a passing grade in the course.
