ESA Assessment

Hi so thats me done two assessments in 2 weeks ESA today PIP a little over a week ago
Todays assessment has got me a bit baffled and anxious I have to say - the assessor explained that if during the interview he feels he has enough information on one condition he will end the interview at that point. He started with my physical problems and when at that point said he had enough - I asked did he not want to know about my MH problems he said no based on my physical problems he had enough - I explained that Im currently in Support group and have been for some time based on MH but its in the last 18 months - 2 years that my physical health has suffered dramatically - he then said he doubted I would have been placed into the support group on MH grounds as it doesnt meet criteria (i have severe agoraphobia and anxiety)
Now Im in a turmoil that although my physical health is bad they may well put me in WRAG as they think I can go out .... or worse still I could lose the ESA completely ???
Has anyone else had the same from assessor stating they stop the interview if they have enough info ? is this normal last time I had an assessment was about 3-4 years ago with ATOS this was either Maximus or Capita
I thought descriptors had changed for PIP have they changed for ESA ?

The assessment was in my home - my GP sent letter and form requesting such due to my agoraphobia - he was very descriptive about my condition I learnt so I was very pleased

Sorry it also meant to add I think he meant the condition agoraphobia and anxiety doesn't put you in support group ... But I was a little confused by his statement and a bit panicky

Oh sorry I thought of another question - do DWP decision makers go solely by assessment or do they look at your additional info too as I do have a lengthy 4 page report from Community Mental Health in my evidence ?
