ESA reassessment after six years

I have been in the ESA support group for six years and today I got a reassessment form.  I am gutted.  I still haven't recovered from the PIP assessment.  I didn't have to appeal the ESA but I had to do a paper appeal for PIP, which was successful, but it took so much out of me.

There seems to have been a change of assessment provider.  Do you think this might be the reason?
