Hey. Well if you lost your virginity to her, then yes. That is rape.
There are some people that have had sex in the 7th grade. Maybe not too many, but it does happen. It's completely normal to be uncomfortable talking about things like this, but if you try to talk about it, the results will be great. It sounds like this is really taking a lot out of you and scaring you a lot, and you should get help. Just keep trying to tell an adult.
