need help dont know what to do

i am a 24 year old man,
i am a marine and have been for a while

i spent this 4th of july weekend with some friends at a hotel, there was one girl over there that kept trying to hit on me, i kindly informed her friends that i was not intrested. she kept trying to get me to go back with her to her place, with promices of beer and such, (i was the only one drinking in the hotel room) i told her no thank you and went to sleep, the next day some of my friends told me they were going to a party out in town, and she was takeing them, seeing as i had friends i did not think much of it. when we got to the party there were people playing beerpong, (a fav of mine) and through the corse of the night giving me drinks, once again i did not think much of her being there becouse there were alot of other people. the two friends i had rode with to the party had to take off to the hotel, i was in the middle of a game of beerpong so i asked if i could get a ride later when i finished. they told me yes so i contenued to play.. after the i do not rmember what happend after that.....the next morning i woke up in a bed with no cloths on.. the girl that was hitting on me was laying next to me.. i freeked out.....my head felt like there was a jackhammer in it and my leg hurt bad... i asked her what the hell happend and she told me that we had sex... i instently felt dirty and ashamed.....like there was a lot of little bugs on my skin that i could not get off...i asked her to please give me a ride back to the hotel and she did...i know its not normal for a guy to fell like this but i fell so sick and isolated.. i dont know what to do... i cant tell anyone, they will laugh at me ... i had work to day to i have been trying to act like nothing happend, but when i got a moment to myself i cried like i never have before. the dirty felling wont go away, and i feel like evreyone is looking at me...can someone tell me what to do to make this stop Tweet
