You're bored out of your mind.
Some introspection is in order. Think about why you're studying what you're studying. Is it to make money? To please someone? Because you can't think of anything else to study? Inertia? To use as a steppingstone to graduate work?
None of these are good reasons to study a particular subject. Even the steppingstone to grad work can often be accomplished with some other major—and if your path is different from others', it may help you get into grad school.
This even means med school. I knew a guy in college who was pre-med and majoring in business. All of his peers were majoring in biology or chemistry, with a small smattering of physics majors. He was the only one in his class (and we were at Boston University, which is not a small school) with that particular combination.
Now think about what you like, and what you're good at. Don't think you can make a lot of money? I got news for you—most people who attend college will make more than their peers who didn't go. This is the case even if you don't finish college.
Pleasing someone else (say, your parents) is a fool's errand. They are not living your life. You
are. You can be nice and still tell them you are going to dance to the beat of your own drummer. They will get over it.
If you can't think of anything else to study, talk to the people in your school's careers center. Even if you have a certain profession in mind, they can probably let you in on other ways to get the job you really want.
And if it's inertia, seriously consider getting a medical workup and even scheduling a talk with a counselor. I am not a doctor, but if you're depressed, there are treatments out there.
You don't have to continue this way.
