My advice is to just try to look past all the words of your parents, and instead note their feelings. They are likely feeling concerned and protective towards you, out of love. Their words might not always make sense, because sometimes humans have a rough time communicating when strong emotions are involved. I think it is best to just take away from the situation that your parents are protective and loving, and try to take comfort in that.

I am a 27-year-old woman, and I can remember being 19. So much has changed when it comes to my perceptions since then, so many things learned, some of them the hard way. But I can also remember how it felt to be 19, and that feeling of needing to try, explore and learn everything for myself. It was a very normal feeling, yet also made it difficult to understand some of the advice and concern that I sometimes received from people older than myself (also totally normal).

I think it's all just a normal part of life, albeit sometimes frustrating, confusing or difficult. Try to have patience and understanding for your parents, as they are likely struggling with trying to balance letting you bloom into an independent adult, while also desperately wanting to protect you from everything.
