I think my ex’s new girlfriend hexed me

Hello! So my ex boyfriend’s current girlfriend says that she practiced witch craft and calls herself a witch and always brags about it (we work in the same establishment). I have a gut feeling she has put something bad out to me or has tried to hex me, she has even made a snide remark on Facebook about it. I really want to find out if she has done this to me but I have no clue if it’s really possible or not, she’s 33 and I’m 19 so she has a lot more witchy experience than I do
