I'm failing college and that means I will not only lose my friends and girlfriend but I'll also lose my family too
What is making you fail college?
I spend most of my time on campus not studying.
It is good to recognize why you are failing. If you need help it is good to reach out and see if you can find a tutor.
I will try to put more effort in studying
Thats great! If you still need help your school has a resource center where you can find help if you need it.
