Dont know what to do

Everything have been getting worse my depression about it. The flash backs the feeling of being alone the disconnection to other people. Not wanting to talk to anyone about it. I'm having a major set back about my rape to the point I had a nightmare about it to the point my friends and boyfriend had to dump water on my head to wake me up because I was punching and hitting a wall and thrashing about to the point I ended up hitting my boyfriend in the back and waking him up and when my friends ran in from the other room I ended up hitting my best friend in the face. I don't remember the dream at all I only know this because they told me after I woke up. They tried to wake me up other wise but it apparently just made me even more violent. And now because of it I have two majorly bruised hands that people are asking questions about and I don't know what to tell them even. I just don't know what to do. My rape happened two years ago and its getting worse and not better
