Turns out she had a blood test a year ago. Was a general check up - nothing was found.
No, browniebaobao, I did not force her into doing anything - in case you have some funny ideas about sex or whatever

. It's just that we had a night when we sort of opened our hearts and told each other everything.
She previously told me about this incident already, but she didn't say she was raped. She merely said she was molested. She only confessed she was raped, during that night we were frank to each other.
Well, she generally don't have any phobias. She only have some discomfort about being too close with guys she doesn't know, which is understandable. Other than that, it's just the usual fear of spiders, insects, etc.
And I've gone through the whole damn list of STDs on the wikipedia. They usually have symptons within a month or two. Judging how it's already four years...
And for the guy who photocopied the information about AIDS, thanks anyway.
I guess I can only continue to support her day by day, and help her recover bit by bit. Thanks for those who were concerned, and to those who replied with useless or nonsensical remarks - may God Bless you.
