no ive never took a seizure before just one on the 4th of april 2015

Hi there I took a car out on a PCP contract for 4 years with Mercedes in August 2014 I took a seizure on 4th April 2015 still no sign of getting my licence back but I've never missed a payment on the PCP agreement this has nearly been a year since I took the seizure and still paying every month I can't see a way out or put a plan together as Mercedes aren't interested although I've informed Mercedes of my situation but there not interested as long as they are getting paid every month,if anyone could give me some advice on what to do I would be most greatful especially in finding out how soon I could possibly VT the car back to them as I'm partially disabled and struggling to get by with having to pay for this car every month it's seriously effecting me and my family at this moment I can't just hand the car back because it would blacklist my name. I think I need to pay at least half of what is owed on the agreement but I just can't keep this up its having devastating effects on my life having to worry about raising the money every month for something that I can't even drive,if anyone can help or point me in the right direction it would be so much appreciated with kindest regards Scott thanks in advance
