My boss is always mean to me all of a sudden , like everything I do is wrong?

despite the fact everything at work seems to be going fine , stuff is selling and never hear these same critcism from the customers.

it almost borders on abusive , like seriously even if i make one minor mistake i never hear the end of it. this person has a mean dark side to them , like truly miserable
