It sounds like you have not found what you want to do/study yet. What your parents want for you probably is working against you now as you have to live your own life. Their pressure is probably making your resistance greater rather than helping. I would do some daydreaming and make a plan I liked for what you would like to do. Maybe you would like a little job and take some courses on your own time while working (I like to use what I am learning at the job I am working)? Or maybe you don't really want to study right now, you'd rather just make some money, see what the work world is like, what living with friends or alone might be like instead of with family, etc. Look at some magazines and books and fantasize what your ideal situation is and think of ways to go toward that.
