Nightmares

This is gonna be long but please read. I been extremely sad. I’ve always struggled with depression .. btw I’m 16. I have these reoccurring nightmares. They probably happen 2-4 times a week. Back in April, I was staying at a friends house. Everything was cool, we went out to eat and did stuff with her family. I guess I fell asleep early one night and I woke up to my friends dad touching me. I looked for my friend and she wasn’t in the room, she was downstairs getting something to eat. I told him to stop and he kept touching me, he told me that he wanted to take care of me. Keep in mind he gave me $40 that day it happened, I took the money ofcourse I didn’t really think much of it. I was like okay thanks. Stupid🤦🏼‍♀️ So I guess he thought it was okay to pay me for sex? Anyways, his exact words were “I see you flirting with my daughter, I wanna see how you get down. Meet me in the bathroom at 2am”. My friend came in and he stopped and left the room. I was shaking and trying to hide my tears from her and I stayed up until about 2:30 scared that he was going to come in. I went to sleep with his daughter sleeping next to me and he came back into the room at like 3:30 with his hands in my hands rubbing me and I was so in shook. He tried to force me to go to the bathroom and I wasn’t going for it. He was grabbing my hands really tight, like it hurt. I kept resisting. He left the room when he realized I wasn’t going to leave. He couldnt exactly make me leave when his daughter was laying asleep next to me. The next day was extremely awkward and I tried to stay away from him as much as I could. Now I keep having nightmares about it. The nightmares feel so real, I wake up in a sweat and crying. I feel like it’s stupid because he didn’t exactly rape me .. It just traumatized me. His face is like planted into my brain and I can’t get it out . What can I do to stop these nightmares?
