Award length

I have spoken to someone at pip and have been award pip both enhance rate the person told me that the award is from 27may 2016- December 2016 is this right as i was only re assessed in August as my other pip was awarded until May 2017

Thank you for responding I have received the letter and it says may 2017 I'm still appealing the length as my condition is no where near looking to impove in the next 9 months if my condition has worsen and from when I first applied for pip would they extend the end date this is an award after my review after I was on the lower rate for both for 3 years and now on the enhance rate for both I now doing a mr on the length but don't know how to provide that my conditions is more long term.
P.s may 2017 is my original end date before I had my review

Thank you once again well I have been on the same treatment for 4 years ( arthritis degenerative disc and severe Depression and anxiety) and no improvement it's only been getting worst, my award is til may 2017 so that mean another review in February. There would defiantly be no improvement as I'm not able to able for the things I need mobility car blue badge etc when I was first award pip in 2013 I didn't try to appeal cause my mental state is all over the place and for people like me there is only so much I can take. That been said I like to be organised because I understand patterns and get extremely depression when things are not in place. I can't get a taxi due to things that have happened in the pass and I don't deal well strangers I have no friends I only have family and I depend on them a lot but I feel like this is going to become daunting on them as there's not much I can do I feel like hanging in the towel and calling it a day cause all falls apart my children will have to live with my mother and I can't live with out them... I've been so patient with dwp I don't know if I could cope if they said no to a reconsideration
