PIP rejection

Hi. I have been refused PIP and need to appeal via Mandatory Reconsideration. There are a lot of discrepancies in my report as well as important information being missed out. Some examples are: I do not use public transport or mix with other people due to anxiety and fear of being exposed to infections and triggers. I also struggle to engage with people face to face because of these reasons, therefore I avoid doing this. I also cannot plan a journey on my own due to my anxiety. I also suffer from fatigue and therefore is not safe for me to cook a meal. However, the Assessor has stated in his report that I can do all of these things! He even said I do not suffer from anxiety or fatigue! I have COPD, Asthma, Crohn’s Disease and Generalised Anxiety Disorder. I have recently started taking antidepressants and start counselling next week. I am also on medication for my COPD and Asthma and have regular appointments and respiratory tests. The rejection letter also stated that because I can make a cup of tea that means I can prepare and cook a meal! Please can you offer some advice on this?
