I just got my letter back about my MR pip decision nothing has changed the decision letter is the same as the last decision letter there is no mention of my idiopathic pulmonary fibrosis there is no mention of my autism spectrum disorder and does not go into great detail about my mental health these were all sent to the dwp when i rang last week to ask my my MR had taken so long they said there had been a mix up i was then passed on to a supervisor when i told him about my ipf he said whats that so i told him its  a very serious lung condition and about my autism he then said i have all your info here and will look at it again i was awarded the enhanced rate for the last two assesements but this time only standard rate for daily living needs and standard rate for mobility needs if anything my health condition has got worse which i told the supervisor this its says i can stand and then move more than 50 metres but no more than 200 metres unaided i dont no how far 50 metres is because i dont carry a measuring device with me alls i no is when i start walking i have a coughing fit so it looks like i will have to go to an appeal which will be more stress and anxiety as if i have,nt got enough going on already any advice would be more appriciated...... this was written by my partner because i,m to upset to write
