Well whatever you do, don't go to uni. You seem like you don't want to be there and that isn't a good thing at all. Speaking from experience of going to uni when I felt like I didn't want to be there, or continue after the first year, it is much better to just sit it out for a bit. If you find an alternative you like instead, then you can keep at it, if it doesn't work out then you've got the option to go back to uni after that, maybe even with better grades that you'd have expected when you initially applied this year.
Since you've got plans for a business already (assuming you have some plan here) then I'd say to follow that and see where it takes you, worse case you go bankrupt and go to uni the year after, 3years+a masters =4yrs, only 2 years left until the bankruptcy is removed from your record, so no sweat....Last part isn't srs advice btw, disclaimer.
