Hi KP,
You answer each question based on how your conditions/symptoms affect you on a daily basis. The impact they have on your life, and the difficulties you experience because of them.
I also suffer from a few of what you've mentioned, including waiting on an assessment with the Adult Neurodevelopmental Team for possible ADHD/Austistic Spectrum Disorder.
I also suffer from Vitamin B12 deficiency, and the likelihood with that one is that they'll either tell you to take a spray or tablets for it, or if it's really bad, then you're probably going to be told you need regular injections.
Hope this info helps
Chris.
