Appealed as far as I can, now given up and fed up!

I got awarded 15 pts from none and moved into WRAG on appeal to FTT. (having been on incapacity benefit for many years) As I won't get income related ESA I appealed this decision to try to get put in Support Group. I had GP's evidence, and a well put together submission with several valid points. I appealed to the UT - who initially said there was an arguable case so agreed to look at it. The Sec of State even agreed it should be looked at again. But the UT judge then said the FTT had come to a correct decision and dismissed my appeal. I have asked for permission to appeal to Court of Appeal - but permission turned down - by same judge who said FTT were correct. To go further now costs money and the risk of costs being awarded against me if I lose. I have very reluctantly given up but feel that the system was very unjust - the Tribunal picked up on anything I can do and ignored all of the things I can't do. In the end we were arguing over moving 1 litre and 0.5 litres and my GP's evidence supported me being unable to move the smaller amount. For the first time in my life I feel the justice system let me down. I had a very good case but my appeal still not allowed. Anyone taken a case any further with results??
