Wait… your parents don’t care if you drop out, but if you do drop out, you’ll be disappointing them?
Pretty sure one of your premises is incorrect.
Get therapy to help you work through these feelings. Stick with your classes until the end of the semester (being out a lot of money won’t make you or your parents feel better), and then forge your new path. If that doesn’t turn out as exciting as you hoped, then at least you’ll have some credits under your belt with which to continue college.
