What is it about your course that you don't enjoy? The course, the location, homesickness or lack of friends?
You shouldn't worry about what your family think just yet, let's not cross that bridge for now. You say you're in an amazing place, not many people get to study abroad so this is a great opportunity for you. It's December now and I assume that the semester ends in June next year? I think you can hold out until then and then make a decision, who knows things may pick up and you may start enjoying it.
