Apparently it was worth spending six days filling in the form.
I'm extra pleased since I only received the "we have got your form and are processing it" letter on Saturday, so I had been anticipating many weeks of waiting. As it is, this is all sorted out for a couple of years and I don't need to worry about it.
The next thing I need to worry about is that I've been called for Jury Service. Which is everyone's civic duty, and ordinarily I would be entirely in favour of going to sit in a court as a visibly Disabled Person. However, various parts of my health, most notably the arthritis in my spine and associated neurological pain, have been so terrible lately that I don't honestly think I am capable of sitting still for hours on end. Also, my chronic fatigue means that I am not always able to take in information presented orally and I rely on adaptations like a voice recorder and laptop for taking notes at uni, neither of which I believe would be allowed by the court. So I have to write and tell them that. URGH MORE BUREAUCRACY.
