Sorry to hear your problem Johnboymartin, I think you may be eligible to apply for a "Hardship Payment" and depending on your daughter's age I would think you should have no problems applying for this.
I don't know if you receive housing benefit or help with council tax, but it would be a good idea to check if these have also been affected, if they have been affected then I suspect your local council who are now responsible for these payments will contact DWP about what they should be receiving and pester for the outcome of an appeal which should hurry things along.
In the mean time, are there any local charities that appertain to your daughter's disability ? If so contact them and let them know what has happened, asking for charity is a hard step to make but you must swallow your pride and accept the help they will give.
Good Luck, I hope your situation changes very soon.
