What benefit could we claim?

Hello I am on DLA High level & Middle level care. I am on high level of
Morphine, tramadol, oramorph just to mention a few but my pain level is so high I might as well not take them, just can't get on top of pain level.
My husband has been my carer for the last 10yrs. He turned 65yrs in Jan
2018 & received his pension as this happened the next week we LOST all
OF the carers money. My husband has two private pensions off 300.00
per month plus his old age pension which rounds it up to around another
300.00. We don't seem to qualify for any benefits of any kind & since we
LOST carers allowance we are really struggling. Does anyone else know
OF A benefit we should be claiming. I am 60yrs old. I would appreciate
any advice.
Many thanks accy58accy
