Step 1. Go speak to your uni/advisor and just get a bearing on the situation.
Step 2. Consider Suspending studies for a year. If you go now, you can reflect and recollect yourself, pursue other interests and see where that takes you. Like you said, it's not just the course, but you're not sure f uni is for you. Take some time off and come back. Remember, you've been studying all your life, you won't know what else is out there till you go and explore.
Step 3. Look up other options - research and read about ALL avenues in life - not just the ones that go through university. Air Traffic controllers make six figures and you don't need a degree. If stability and money is what you're look for ATC is great. But if it's passion then you need to find what you're passionate about. But if you just want to do a job, look up any job that interests you and watch youtube videos of people working in that field. If you're still interest - figure out a way to get in that job - if it's swapping degrees so be it - if you don't even need a degree - even better.
