The dreaded brown envelope

Good evening
Please can anyone advise me ? I received my brown envelope today I only submitted my additional evidence and was received via the dwp last Thursday I rang dwp Friday and asked to be put through to a case manager I explained again my additional evidence she must have sent the answe same day? Still standard for both 11 points daily living 10 points moving around. I have been on enhanced both parts originally 21 points Daily living 14 points moving around I have arthritis throughout , severe anxiety and last yr was diagnosed with fibromyalgia how can I possibly be better? I had a really bad home assessment ( a compliant has been issued to atos) lots of lies and information given not documented. I have been very ill and have been off work for 3 weeks up to now with chronic pain and severe panic attacks my doctor wrote in detail a letter explains I cannot go out alone yes I work but have to be prompted to get up , dressed, fed and driven to work I've gone from working full time to part time hrs I've never claimed any benefits ever apart from pip I receive working tax credits the assessor documented I worked 3 days so I can communicate , I can drive to and from work and the doctors this is not what I said I said I was taken and brought home I cannot travel on public transport due to anxiety and suffering panic attacks I get brain fog very forgetful my manager has kept me in a job I think creating tasks so I can keep my job but now I'm at the point were I cannot take working anymore? I have no transport? the car has to go by end of Feb I'm too ill to apply for appeal I couldn't attend anyway due to my illnes and now at my wits end would I be better going on the sick? does anyone know if I would be better off financially not working? My husband is a full time carer for his mum and only receives carers allowance I receive 500 per months working tax and £480 per month wages and my standard pip £310 per month I don't get anything else I get support from a lady who looks after me and I pay her to look after me when my husband is not here sorry to go on I don't know who to ask Thankyou

Thankyou Gordon.
is is worth me ringing up and asking to speak to a case manager? I was told by a case manager that they cannot make a decision on additional medical evidence as not trained and additional medical evidence goes bk to someone who can ? basically they have totally ignored additional information medical evidence from my dr I didn’t think the could do this my doctor has written I cannot go out alone need to be accompanied to avoid anxiety panic attacks I don’t understand why they havnt awarded me the additional 4 points am I doing something wrong? and what does taking prescription drugs but no specialist input? Mean ? they are prescribed by my gp. my daughter wants me to appeal but I’m scared as I couldn’t attend face to face it would make me very ill sorry for all the questions
