19F engineering dropout and feelings of guilt

I started engineering at 17, parents paying for my tuition. For a lot of reasons I convinced my parents to dropout of civil engineering in my third semester, from a VERY good uni. Please do not ask me why or motivate me to continue.

I spent quite a bit of money here till now (had scholarship). I feel really guilty. The degree I am going to pursue after this will give me a very high chance to move abroad and get triple the money back and has great job security. I am also confident I can do this new degree in full scholarship.

But I don’t know how to stop feeling guilty. I feel really bad for wasting my time, their money and the overall sunk cost. What can I do?
