PLEASE HELP!!! My it teacher is being a b***h?

Well i tell you the story, i was set this task to do this visual basic program and i was away for 2 periods. Then i came back and try to do the projects in the 3 period and then she mark my work "N(Fail)" due to the fact that i have encounter an error with my program and i did not have sufficient time. Then the next day i was angry with her because she made me do another program and i thought i wasn't fair because i know what i was doing as well as not given enough time.Then she saw me in a bad mood then she yelled at me and say get out of your bad mood and save your wining for your mummy(Scottish voice). I was pretty upset because my mother is not felling well and i told my principal about what happen and she was meant to apologize. However, i try to have to be strong and still continue to go 2 that cl. However she went back to Scotland(her country)and now she back in Australia(my country) and I'm worried that she going to humiliate me more and mock me even more. What should i do?
