A bit of good news for once. After being awarded 0 points on my PIP reassessment, and losing my existing PIP, my mandatory reassessment has just come through and reinstated my claim.
I was awarded a few extra points this time, but I still think I was short-changed. I am now eligible for a blue badge, but not enough for higher rate mobility (10 points).
I could probably take it to a tribunal, but I have a few health issues being investigated which may alter things down the line, so I will probably wait for a while.
Hope this offers hope to somebody else though. The biggest piece of advice I would offer to anyone applying or appealing though is EVIDENCE. For my MR, I provided over 50 pages of evidence including phycology reports, specialists reports, photographic evidence and a paper trail of appointments, referrals and prescriptions so they could not lie anymore.
Above all, have hope and fight for what you deserve.
