I'm worried.. I got taken advantage of and I was a virgin, its been a 1 1/2 weeks, still sore and bleeding ?

Question

I was at my friends party with some people I usually dont hang out with and some one gave me a drink that tasted like watery juice so thinking that is was a mild drink I drank alot but it must of had alot of alcohol because I was so drunk and this guy i work with ended up taking me home ... I was sleeping most of the time and barely remember a thing except waking up because it hurt ... I remember him being rough and doing it alot. I told him to quit and it hurt and that I was a virgin but he didnt really quit. I couldn't really function enough to do anything about it. After that for about three days I was bleeding,, but had no period symptoms and it was very sore. It still is now and spotting blood a week and 1/2 later... Im pretty sure he didnt use protection and I did take plan B ... Im so scared. I was a virgin before this and I am sooo mad at myself. I don't know what to do.
