I am so sorry you have experience those things. It was he who should have not done those things to you, how can a 3-11 year old have any power over an adult? Not only would he have been physically stronger, but also would have had psychological power over a child.

I am sorry too that no-one ever noticed and that even now your Grandmother doesn't believe you.

Have you told your T and your care team?

Hugs to you, no-one has the right to do what he did to you.

Take care. Soup
