Hi Tina,
I don't know a thing on how the welfare system works, sounds like a horrible situation you are in.
I know this prob won't help but if you could get letters from MABS, your GP and St Vincent de Paul and get them to state what a toll all this is having on your mental and financial health and the grief and hardship you are suffering it might move you up the list of review a bit. It might make no odds at all, but it can do no harm.
A saying I was always told is if you have two babies the one that makes the most noise gets picked up first!
best of luck
