ESA and Support for mortgage interest

I qualified for mortgage assistance but have now had the money deducted from my esa. The reason is that i have lodgers and my income is too high I am in the support group but the benefits are wiped out becuse of the deduction. I have a large mortgage and after money paid directly to my building society there is a shortfall of £1000 which is made from rental income. I am in efffect nearly £500 out of pocket with only a tiny pension and lower DLA allowance. I have only £260 to live on for a month, this barely covers fuel bills. The support for mortgage interest is supposed to avoid evictions but in my case it is going to accelerate my problem and the only money i can get would be not paying sll of my mortgage which is already subject to a court order.
Surely this cannot be right, I am looking at selling and downsizing but that all takes time and I still am broke and fast running out of ways to get money, loans from friends and family etc
