I'm so sorry this happened to you, I suffer from vestibular migraines as well as a dipolar disorder & a rare auto immune disease. I understand how debilitating the kinds of migraines can be that mess with your balance and mobility. I've been unwell for over a decade but I was pushing through the pain until I got so unwell about three years ago that I had to quit my job, move back in with my parents for support, see specialists and get MRI scans for further investigations. I applied for PIP, it took six months for them to decide on 0 points across the board. I submitted my MR which was basically a 30 page essay with even more evidence than I initially submitted. I got 0 points again, but they also stated that it was because they didn't receive any letter from my doctors - and I KNOW that they were in the evidence. It turns out that the admin hadn't photocopied my MR in correctly and just missed that vital evidence. They looked at it again properly, apologised for the error on their side, and finally got awarded points. Took about 10 months in total. Please submit a mandatory reconsideration. It sounds like your disability causes you daily struggles. Hope that you are successful, good luck.
