Esa Medical again

I have unfortunately been on benefits for many years due to botched surgery and I have had many many medical assessments. Fours years ago I had to take my case to Tribunal when I was placed in Support. I am now facing this all again with a medical in March.

I provided medical proof having lost a week as the paperwork arrived over Christmas and have only only been able to get a doctors not today as my doctor retired. I will send to the assessors asap. Is there anything I can do in the meantime to avoid having to do all this again. Can I ask them to look at my case again this time including the doctors note and get them to recognise nothing has changed since my appeal. In Fact I am worse. Why anyone would think I would choose to live this life and survive on £500 when my mortgage is £400 I just don't know. Could anyone offer any advice. I am in Streatham and the advice centre I used in Clapham is now closed.
