Teen age girl had forced sex

Hi
I am a 16 year old girl. A week ago, it was like Friday. After finish my ballet class I went to my friends home and partying. I was a little bit drunk after and two guys took me to a bar and I agreed( I don't know how I could agrees that coz I know it us not ligel for me ). Anyway, we went in and it's was crazy and loud. I wear a tshirt and a pair of cotton pants. But inside my shirt and pants I had my ballet leotard and white tights on. I don't have time to rake them off coz I went to the party after.

Things happened. I was dancing alone and suddenly a man grabbed me out of crowd and push me to a room. I saw there were about 7 guys in the room and a woman with them. They started took off my clothes and I was shouting and crying but it didn't help. They saw my leotard and tights and said all those dirty words and push them off. I was a virgin and those guys were really happy about that. A man ripped out my clits and started raping me. One after one. There was blood on my leotard and tights I didn't have any other feelings other than pain. Seven of them raped me in my vagina and ass. I thought I am going to die. About three hours (around that). They all finished and left me alone in the room. I was no longer drunk and afraid as hell. Their cums went out from my vagina, ass and my mouth. The woman left in the room spanked me and called me a s***. She grabbed my tights and push it into my vagina and left. I couldn't feel anything, it was nothing in my mind. I stood up and try to put on my clothes and ran out of the bar.

After I went back home, I didn't tell it to my mum( I dint have a dad). I took all the clothes off and my dance suit. Wash them like for two hours. I feel my vagina was swolen and hurt , my ass was like on fire I went to the shower and cleaned all the blood and cum on my body. I didn't go to school this week coz I couldn't stand or walk. The tights us still in my vagina, I couldn't take it off. It was really deep in and each time I try to touch my vagina it hurts. I told my mum I was sick so I don't want to go to school.

What should I do? What is happening to my body? Will I get sick or illness? Will I get preg? Am I still a virgin?? Why my vagina is still bleedingand swolen( is it becouse there is the tights in there)? How can I get the tights out? Any other problems or ideas u can tell me or help? Did anyone else get raped before? Will I get STD?

Thanks
