Taking him to court

Im going against my ex boyfriend in court for rape, violent/threatening behaviour and manipulation with suicide and I have the choice to have a screen in front of me so he can’t see me. I’m terrified of him in all honesty. He’s currently in prison and has a huge case involving a lot of people, children, woman and men. Showing my face might send of a message to the younger victims not to let this pathetic waste of space frighten them. I just don’t know. I haven’t seen his face in almost 2 years and I don’t know if I can bring myself round to laying my eyes on him again.
