I'm so sorry this has happened to you
@DiamondBug - you are not to blame and you are not gross. You are not what has happened to you, you are not defined by someone else's actions. Also you are CERTAINLY not responsible for whether or not it happens to other people - I'm not surprised you found that really hard to hear as it's simply not true. I really battle with that kind of thought, but I am told/and tell myself over and over again that THEY are responsible for their actions and whether they do it again. It's hard enough to deal with the trauma without taking on the responsibility of someone else's. You've done what you needed to do to survive - and you're here.
I also find it really hard to say things, I tend to also write things down and pass them to my T and not look at her. I also am currently disclosing little bits at a time, so that I can suss out how well she deals with it. Sometimes I want her to be totally unshockable, but sometimes it is healthy to see someone respond to what you tell them because it helps you realise that it wasn't ok, it wasn't normal or the way you should be treated.
In terms of the boundaries/hugging things - I recommend letting your T know that you're feeling like you want a hug etc. that way it gives him a way to inform you of the boundaries without you having initiated contact and him "rejecting" it. It's more like a discussion, and then you can establish what works. It's understandable that you want contact - as you say, being isolated with this and being let down by the police/school/your parents leaves you bound to seek comfort from someone you feel more able to support you, and this could be your T. Try to remember, any boundaries are there to protect both you and your T, they aren't there for the sake of it, and they are not to make you feel bad, much as it can be hard when someone doesn't give you the physical comfort you want.
You are being really brave, and showing great strength working towards your goal of sharing your story.
