ESA Renewal Form

Last October I was 'successful' in getting ESA (wrag), (although I was never called to do any activities). In the report, though, it said I would be fit for work in 6 months, even though I have a CHRONIC mental health problem (depression/anxiety/perhaps phobia of people), so I was expecting a review any time from April onwards. Today I received a Limited Capabilty for Work Questionaire form. I'm not sure but I think it's a bit different from the form I got last year - I think it was called an ESA50 (I have a copy somewhere). I was wondering if you would be kind enough to advise me how to fill it in? Quite frankly, nothing has changed since the last time (and i'm still waiting for a psychiatrist appoinment). Is the form i've got today different from the one I got last year, and will I need to go for another horrendous medical? As things haven't changed can I just copy what I wrote last time or even write on the front No Change or something. Also, since there has been no change I would assume that I should get the same result as last time (although I hoped for longer than 6 months and to be put in the support group!). If the result comes back 'fit to work' could I appeal, especially on the grounds that last year's result for the exact same thing said I wasn't fit for work. Should I ask my doctor to write a letter (I didn't the last time but I think they contacted her) Please advise me what to do as I am very worried and it's taken over my life.

Could you please direct me to the updated guides because the only one I found on this site had 21 questions, but I have the new form and it has 17 questions. thanks
