Help me find my mum

Hi all!!

I don't know if this will work..

My mum went missing in 1998..
Just vanished.
My brother was in jail.. My older sister moved away.. My little sister was sent to a foster home and I was sent to my fathers..

Our family is split up and we hardly talk but we all share the same thought as to where I mother could be? Or what happened to her??
I was 6years old when she disappeared.. I made a promise to myself that I won't rest till I find her..
Her name is Joanne Butterfield
She was on Australia's most wanted and a few years ago we were lucky enough to get an episode on missing persons in 2006.

I nearly feel guilty raising this money to find her when there are kids with absolutely nothing..

But our family needs closure and this money will hopefully be enough for me to head to Queensland and open the case again! I will not stop until I find her!
Please help me!
Anything will help :)
