I think the way you feel now is you panicking about what your next steps are. I don't believe that dropping out was not a choice you took lightly and you gave it great consideration. In the end, you don't want to waste time and money studying something that you hate.
If you still want to go to uni, research courses and universities that interest you. There is no rush to go to university if you feel it isn't for you - you could look for apprenticeships, employment or internships. Take the time now to decide what you want to do, and then the path to get there. Your parents won't be disappointed in you, they are seeing you take charge of your future.
