PIP assessment

Just wanted to vent that I asked for a reconsideration of my mobility component after getting DLA for several years with a degenerating condition and having my mobility element cut by PIP. Have not had the energy to appeal as i'm in and out of hospital fighting cancer. The thing that angered me was that, having been in bed for 10days before the assessment, my sons settled me on the sofa for the visit, I never moved from this position during the assessment, but in the letter rejecting my reconsideration request, this woman said she observed me walking with a stick etc. Me and my sons know these statements to be utterly untrue and I m going to contact my local MP about it when I am feeling stronger.
