One bloke said he was classed as disabled because he lost an eye in a fight.
Being classed as disabled is not a great help and I'm not even sure there is such a thing in relation to benefits.
My son has Downs, SLD and a severe hip problem. His benefits level is based on need to support him in life. I could go on a full scale rant here but won't!
I have an epilepsy diagnosis - a very lazy one by the consultant - and in some circumstances am classed as "disabled." This relates to car insurance, travel insurance etc. and means I cannot be discriminated against on health grounds. This is classification for protection not entitlement.
You're task is to establish your "need" for support which will determine your entitlement. It's all about qualification and matching criteria. If, for example, your condition can be proven to limit your capacity to work this might qualify you for support of some type.
Do not expect this to be easy. In 28 years of fighting for my son it has never been as bad as it is today. I'm not being political but this government has relentlessly imposed cuts on the disadvantaged for 6 years. Everything is getting harder and harder to maintain the status quo. Hitting those unable to fight and unlikely to vote is easy.
We used to joke the LA family file only contained one piece of paper which said "Don't mess with these people - they'll win."
It's true we did win, always. Today though it's very, very difficult. I'm even fighting for the reinstatement of Tom's blue badge. The renewal has been refused after 23 years. The badge costs nothing and you don't improve from SLD and Downs. Bastards!
