WCA QUESTIONAIRE MEDICAL EVIDENCE

Please can someone help? I am on ESA in the support group for the last few years. I have today received a WCA questionaire and this will be about the third I have filled in in last three yars. It has come at exactly the same time as I am going through PIP assessent. I was on DL:A indefinate award. It has made me unwell gathering all the medical evidence on my medical conditions and I have a very thick A4 folder of evidence with all my medical conditions. When I first claimed DLA it was because of my mental health but since then I have become very physically unwell too.

My question is how do I send medical evidence to two different departments both at the same time? As itt was I was sending PIP all my orginals as I couldnt possibly afford to get them uch money. copied as it would cost me too much. I found the medical asssessments for WC and PIP who wont help and wont transfer the evidence I send form one department to another. The jobcentre wont copy it n there is no advice angencies who will help. I am not even sure how to fill it in as the link to the members only gides arent working at presnet. My life is not worth living. I am too ill and cannot take anymore. Why have they sent me another WCA and why is it all at the same time. PS they sent it in white envelpe so now i have to dread white as well as 'brown 'post.
