I don’t really know anything about your condition but it reads to my very much like you are trying to hedge your bets, as you intimate at the beginning, and it has become very confused. Also, you seem to repeat the phrases from the descriptor without giving any examples e.g, “…I cannot undertake a journey, familiar or unfamiliar, without assistance, due to the overwhelming psychological distress I feel when I do so” which is fairly obviously a cut and paste from the descriptors.
For me the obvious things to clarify are :-
If you can go out on two days per week unassisted/with prompting what is different on those days to the other five days?
When you say that you ‘cannot undertake a journey’ do you mean that you can’t go anywhere? Can you go to the local shop? (if there is one)
If your condition causes you exhaustion and you can’t go out, does it also prevent you doing other things such as having a shower, or cooking a meal?
Just my two pennyworth..
descriptor (e) cannot go out on any journey because it would cause overwhelming distress - does that apply ONLY to people who NEVER go out?
