Disabled daughter in education 19 - lost uc payments

My daughter is autistic- diagnosed by the adult mental health team .
She has huge social issues but manages to attend college.
She is 19 and revives Pip .
Without any warning I have lost any money towards her upkeep - I am a single parent - work part time 18 hours earn just over the carers allowance threshold so lost my carers allowance.
She receives her pip. I lost £500 with no warning , I’m not entitled to an advance… as I earn to much apparently . Surely if she’s disabled I should be able to claim for some support ?
I’ve bee told she has to claim UC and give me money towards her keep - she has PDA and is very hard work - will not go to a jobcentre- isn’t ready for the adult world - I can’t cope , I’m at such a loss .

Hi I agree you may need specific advice. Do you still claim child benefit for example? (If she is not on UC you can do this for students up to age 20). Could you make some pension contribution so your earnings fall back below the carer's earnings threshold (not sure how much you are over the threshold by - but I think they still disregard half of any pension contribution - you would need to check. I used to contribute so as to still qualify for Carers allowance. If you have a pension with Nest or somewhere through work, you can just set up a contribution but its only worth it if you are only a small amount (eg £19 a week) over the earnings threshold for carers allowance so you put £40 a week into pension and they take £20 off your earnings calculation so you still get the carers allowance of about £67.
Plus of course being an appointee is a suggestion so you can claim on your daughter's behalf .
