Hi celtic, first of all attempted rape is attempted rape!! You didn't ask for that to happen so no "setting yourself" up there!!! You shouldn't carry any blame for what happened to you at all!!!
I can see that that must have been really traumatizing for you though even if that's being "bottled up" it doesn't just "go away". Just the same as the abuse you suffered before, which must have been really painful in whatever way it showed. And perhaps your feelings after the attempted rape both added to, and brought back what happened to you before in a very real way.
It is really good that you're now seeing a therapist though. It can be a long, hard road towards coming to terms with, accepting and moving on........and very few people can do that all by themselves. Make sure you guide the therapy as much as your therapist though. Although some things you need to work on might be really hard, if you find it's not helping, or going in the wrong direction, or going too fast, don't hesitate in letting them know that. They're there to help you.
And maybe you could do with some other support alongside the therapy, do you think?? I don't know if you've heard of RAINN who offer support with rape and abuse, but I know a lot of people have found them very helpful. Attaching the link, in case it might help:
RAINN.org | RAINN | Rape, Abuse and Incest National Network
And of course (!!) we're here whenever you want to talk too.
