Dealing with the aftermath

Last time this year I was Raped. I have been trying so hard to not think about it, but it just keeps popping in my head. I guess because it was around this time last year. I have been having horrible anxiety and since my family doesn't know it's really hard. I don't have anyone to talk to and I'm just at a loss. Does anyone have any advice on how to move forward or if there is anything I can do to make this process a little easier? Any advise would be helpful.
