Help?

I was at my best friends house for their dads birthday. He had several of his army buddies over, many of which I knew bc we have spent the holidays together. Everyone was drinking including me. I had eventually sobered up closer to bedtime but was still a little buzzed. A few people had spent the night bc they were unable to safely drive so the house was kind of full. Me and one of his buddies were set to sleep in the loft area (her on the coach, me on the floor). Just as I was getting ready to lay down, she grabbed my wrist and told me to come “cuddle” with her. I agreed bc I thought she was just drunk and didn’t want to lay alone. (I should mention she’s 27-28, and I’m 16)

After I laid down she started touching on my boobs and tried to put her hand in my pants and when I tried to move away, she’d hold me back with her other hand. She eventually pulled off my pants and kept eating me out and roughly fingering me. I was so uncomfortable and kept trying to leave but she would just hold me in place. She would keep making remarks about how I was such a good little slut and stuff about my body being beautiful and other things, which make it very hard for me to even look in the mirror. At one point I guess she heard a noise and laid on the floor and threw a blanket on me. As soon as I was certain she fell asleep I locked myself in the bathroom and balled me eyes out. There was blood on my thighs and it hurt to move. I frantically tried to call a different friend bc I was in so much shock trying to process what just happened. After several times of calling I had no answer. And I’m unsure how of what to do about the whole situation. And I truly don’t know what hurts more, the act it’s self in a house of people I consider to be family, the fact that I couldn’t count on that friend to answer the phone, or the person I consider to be my “bf” blowing it off when I told him and acting like it wasn’t a big deal bc it was a woman and not a man.
