High school help please?

So i live in canada and i just graduated today. At my grad a lot of my peers received awards and i didnt get any. My mom got pretty upset after and didnt take a pic with me and started nagging right after teh ceremony. Any ways i ignored it but she went all psycho when we got home throwing stuff, name calling etc. I told her that even i was pretty upset about not getting any awards but she kept saying a lot of hurtful things. By hurtful i mean like things you'd never wanna hear trust me. And i know i screwed up and couldve done better but i didnt know what i wanted to do so i took courses i hated and did bad in them. I told my parents that i am coming back for an extra semester to do what i want. I wanna go into criminal justice but earlier i tHought i wanted to do public health. She keeps nagging me and says that im never gonna go to uni or get good grades and im just set for failure in life. I feel so bad :( Like i know i did bad but i wanna improve and do better but this hurts me so much. And i also hid a lot of my report cards in the past and she brought all that up. She keeps telling me about her friend that told her when i was born that i was gonna make her cry someday. And she thinks all that is coming true and im set for failure. I just hate this i need help i dont know what to do
