Planning and following a journey

Hi my partner suffers with mental illness she has been diagnosed with the following mild to moderate cognitive impairment, non organic psychotic disorder, P.T.S.D, alcohol dependence syndrome, dependent personality disorder, depression with psychotic symptoms, anxiety disorder and bereavement disorder. My question is about planning and following a journey. The last journey my partner tried to plan and follow by herself was in 2018 to the hospital to visit her mother which should be a familiar journey involving two bus rides. I would have normally taken her but was unable to because I was unwell. So she tried to plan the journey herself but she could not work out the route of the journey and which bus to catch and which side of the road bus stop she needed to be stood at and where to go once she had got off the bus and she became very confused and anxious and panicked. So I wrote every detail of the journey down for her. So she left to undertake the journey about an hour and half later I received a phone call from my panic stricken partner who informed me she had become very confused and ended up getting on four different busses she had got very confused and got off the last bus in a panic and now did not know where she was. I had to get her to pass the phone to a passer bye who was very kind and gave me their location which was half and hour away from the hospital. I had to go pick her up even though I was unwell myself I did not mind just glad she was safe thanks to the kindness of strangers. I brought her home the journey never got completed as a result of this I now plan her journeys and accompany my partner everywhere she needs to go. My question is to anybody who would be kind enough to answer it is which of the planning and following a journey descriptors does this fit.

Not sure I understand what you mean Catherine sorry if I am not getting it. My partner does not have any problems with the ability to walk her physical health is fine she can also undertake a journey but only if I am with her. My question was and is which descriptor from planning and following a journey best fits the example in my earlier post of what happened with my partner.

Thank you Catherine it is much clearer and exactly the answer I was looking for. Sorry to put you in the assessor's shoes but my hope was that the example I gave demonstrates to at least one other person that she cannot follow the route of a familiar journey without another person but as you say we should not second guess an assessor.
