Hi Dawn
We cannot say whether or not you should put in for a mandatory reconsideration, that is something you will have to decide for yourself.
From what you say I think you have scored 4 points for b) (which is about needing prompting before you go out)- whereas you might argue that you also qualify for f) which means you need the support when you are on an actual journey for the reasons set out in your psychiatrist's letter
