Challenging PIP review decision - about prompting and lack of 'support'

Hello - I want to know what I do about PIP 'evidence' and my long standing unmet support needs for a number of health conditions. Having unmet support needs has resulted in longterm stress, anxiety and panic. The PIP forms seem to assume there are people (friends, family etc) around to help and support or else 'you can manage ok'. I can not manage ok on a number of fronts and I do need prompting on a regular daily basis but I do not have people around me.

In addition the lack of meaningful support from Councils, NHS and charities is quite appalling as we all know. If I (and others) can't get support because no one is providing any - what evidence is there to provide?
