Hi Lisa,
My advice would be to get letters of support from your mental health team, and when you've received them you should send them to the DLA Unit in Blackpool and ask them to review your claim with a view to being awarded care component also.
However, you need to be aware that asking for a review could result in your DLA LRM being looked at again.
We cannot give individual advice on claims as is explained in
FAQ Your local CAB may be able to assist you, if not then try
Community Legal Advice Hope this helps.
