Good for you Karen taking the girls. I hope they (and you) got through that ok. I agree with @Former-Member sometimes that can be very unsettling for kids - or adults - especially in the short-term. In time if the trauma is worked through effectively and gently at a rate which isn't too overwhelming it can be very helpful. I hope it is for your girls. It is very courageous of you to be working with this for them, because it will inevitably bring up a lot for you which is very painful. You are such a good mum.
I can understand why you are worried and anxious. Lisajane is right - you really need someone to advocate for you. I'd suggest VMIAC but I think they are both guys out our way, but I have sent an email to Daniel (who I've spoken to before about other issues) and asked if they have any women working in the advocacy area. I will let you know if I hear anything back. Any wonder you feel frightened and backed into a corner.
My little girl did beautifully reading her part, she remembered to use a loud clear voice and speak slowly, butterflies and all. I'm very proud of her. I managed to squeeze in a walk along the rail trail with a friend this morning between drop-off and the ceremony. It was great to get out, the weather was kind and it was lovely to catch up because it's been a couple of months - we've both had so much going on.
Thanks, I am managing ok at the moment.Things have settled down a bit for me thankfully - I am even catching up on a bit of the sleep deficit finally. My teenagers did the mowing and whipper-snippering this afternoon which was lovely. My 18yo came up from his dad's yesterday to help out. I feel very grateful for it, and it was lovely to see them working together - the camaraderie. My 18yo showed my 13yo how to use the mower. They've done a great job. 
Take care of you.
Hope for an advocate when we need help endures...
Kindest regards,
Kristin
