What should I do?

So i was raped back in october. It was pretty traumatic but i never really opened up about it to people and i just kept it hidden. But these past few weeks i keep having these flashbacks to the night and i would remember how it felt blah blah. I was just wondering what i should do. Like idk if i should open up to people or not. Like its really hard for me to because i might end up crying, and i dont like crying in front of other people, hence why i just avoid telling people in general.
