You're an 18 year old pre-med student and your parents won't ALLOW you to get therapy? Helloooo........you don't NEED their permission! Gee, you could have saved yourself alot of unnecessary worry if you'd asked THEM if you could have the unprotected **!
The odds of you contracting HIV by this "route" is miniscule. As an 18 year old who is sexually active AND a pre-med student, this is information you should know. You've been tested and the test was negative. And the needle was clean. I can't believe you called and asked what their needle policy was! What did you honestly think they'd tell you? If they DID reuse needles, what are the odds they'd let THAT nasty cat out of the bag? Of course they use clean needles.............you REALLY got to get that idea out of your head!
And if you're so freaked out, why wait until the end of the semester to get the oral test done?
How should you cope? I would suggest, first off, to educate yourself! Then go to your college infirmary and speak with someone there. I know they deal with HIV fear and hopefully that will set your mind to rest. Or call an AIDS hot-line. Sadly, they abound. Get tested as many times as it'll take to convince you.......
You have a lot of options but, personally, I think sitting around watching videos of people who are really living with the virus is just weird. THAT makes you feel better and relaxes you? On second thought, I think you should opt for the therapy ASAP.
One hopes you have learned your lesson.

This link is from someone who also turned his life into needless fixation on getting HIV when he didn't have it. I hope it helps you see that you have other things in life to think about, such as being young (I am guessing you are young) and having the opportunity to do just about anything you want.
