Hello everybody hope you are good.i have recently made an application for a change of circumstances. I have arthritis in my hips and knee and back.i am in receipt of enhanced mobility. However I have just received a letter saying I have a telephone assessment on 30th July.i have been to 5 tribunals since 2012.i am very tired of repeating my condition.to them as a result of that I suffer from depression. Can I cancel the change of circumstances request as I can't face an hour and a half of the same questions again.thankyou.
