Hi,
I can understand how stressful this could be as it's seen as a big step in life going to university but I hope I can help!
Firstly I would look into any other courses you may be considering, really go into depth on looking at what the modules of each year offer and see if this suits you. Create a clear list, whether this be written on paper or on a computer, on what courses you want to study and say why or even why not. This will give you a summary of research and hopefully weigh out any pros and cons.
Law, may still be the way you end up going and that's great. However if you do find yourself in a situation where you are not enjoying the course you are studying then that's okay! This is a common thing to happen where students have ended up studying something else, even someone I know did that from Business to Film Production. So if this does happen don't panic it's not permanent and there will be people at the time to support you on what to do next.
I hope this helps and good luck.
Kind regards,
