Hi Keith, it must have taken a lot to tell your mother that, real respect!!!
And it's good that you've managed to "break the silence", it really isn't something you should have to keep to yourself, cope with alone/without your mother there to support you.
You didn't chose for that to happen, it wasn't your fault.
Now initially maybe your mother might struggle with it, ideally any mother would find it hard to hear that their child had been sexually abused, but I really hope she comes through for you.
But you know, however she takes it, we're right here for you regardless.
