Hi again Daz
Yes, definitely speak to your Job Centre Plus advisor and ask about local employers who promote their programmes to help get people with disabilities back in to work
https://www.gov.uk/looking-for-work-if-disabled There is some support available (not enough in my view but that's another story) but you have to explain your situation and ask for it.
For the DVLA and driving, it's really important that you ask you GP (see my other reply to your earlier post -- glad you got registered

with a GP) to confirm whether or not you're fit to drive. They will be able to either do a simple sight test in the GP's office or else refer you to a specialist if there's any doubt. If you use a high street optician, they will be able to do the same, if you prefer to use them. Hopefully you'll still be assessed as fit to drive. But if not, you must tell the DVLA and pass on to them the information you get from your GP or optician. They will make a final decision about your ability to continue driving. Motoring offences such as driving while medically disqualified can lead to deportation if you've lived in the UK for less than 10 years as you might be deemed to "present a threat to public order, public security or public health". If you've been resident for more than 10 years, deportation can only be done "in exceptional circumstances" and would be very very unlikely for this kind of thing but you can still be fined heavily. So don't take any chances, get a health professional to confirm you're alright to drive.
One final thought, in all this, though, try to keep in mind that your medical condition
is not your "fault" and that you've done nothing wrong or made any mistakes. From what you've told us, you've supported yourself and your family in the UK since 2004 quite happily and with self-reliance. It's very common for people who become disabled (whether you think of yourself as being that) to start to feel guilty about their situation and somehow "imposing" on others or on society. A healthy society is one that takes care of those who need it and doesn't judge illness or bad luck. And that's what I hope we all live in !
Good luck !
