How do you know someone did witch carft on you?

I have noticed horrible things happening to me ever since I got into a huge argument with my sister. Yesterday I got into a car crash. Last month I have covid Doctors claims it's normal for people to get sick of covid. But I suspect my sister is doing some witch carft work on me. How can you tell some one is a witch or did socery to you.
