Kelsey, I'm glad that you have felt able to tell us about those things that happened to you, but which shouldn't have happened to you. It must have been difficult keeping this to yourself for so long ~ a problem shared is a problem halved, as they say.
Perhaps you could now tell your Mum ~ you might feel better about it, if you did. You were ~ and still are ~ very young. It's a lot to keep to yourself.
Take care!
