It could be worse dude. You should just be honest with your parents right now. Stop putting it off. Take some time off from school if you need it. Find out what you actually want to do in life. I had a similar problem this year, I was in commerce and I hated every class. Couldn't focus cause I had no interest in the course material. So I decided to drop all my business classes this term and restart next term in education. I'll be a phys ed teacher in 2.5 years. Dream job for me dude, cause I'm not all about the money. I'm a believer in all you need is love.

It'll all work out as it should.
