What shout I do?

I have given my exams of FSc (medical). After this, my college is almost done, the only thing I'm worried about is my next step. My parents want me to do nursing and I was ok with this but now that I think about it, I don't feel like I want to do it. Even now, I tell myself if I do it, I will gradually got interested in it but on the other hand, I also wanna do something that I like. The most worrying thing is I don't know. I don't know what I want to do? And it's really hard.
