PIP mandatory refusal

hi everyone ,

ive just been refused the enhanced mobility part of a PIP appeal decision I get 10 points for the mobility and moving around but always seem to score zero in planning im recovering from an a serious injury from 20 years a go it eventually to a point where I had post traumatic osteoarthritis and was getting by in a lot of pain and a yearly steroid injection which became less effective or didn't work after 3-4 years and the pain got unbearable so my option was to have an ankle fusion to relieve the constant pain which ive successfully had done now over 8 months a go after a 16 month wait I also suffer with depression and generalised anxiety disorder which im medicated for I live in a new build apartment block second floor and rely heavily on the lift as climbing up and down stairs is too much of a challenge and the lift as just been repaired after a month of not working I know I don't get out much as its so tiring I can't walk unaided and rely on my 72 year old mother to do my shopping ironing and making meals 2-3 times a week which is a great help and any appointments my mum or partner can drive me there ive worked up until 2019 where my job was impossible as it was manual and involved lots of lifting fitting machine parts and walking and the arthritis was at its peak then im currently taking the highest dosage of codeine but I feel isolated and don't like relying on my mother to do these great things for me I just want some independence and the enhanced mobility which im a point short would give me this as I would qualify for the mobility scheme and would be have an option for a car or disability scooter ive probably only been out a handful of times in the last few years and with the summer coming up it would help me mentally to sit out I have a mental health mentor I see once a week and thinks I should challenge this decision and take it to a tribunal im currently getting PIP standard mobility I have a blue badge and free public transport pass but I can't get to a bus stop because of the location and find it overwhelming going out due to been anxious I don't want to rely on my mum as she's retired but primarily looks after my grandma who is 97 just want to know I have a choice of independance without relying on others ive adapted to knowing life as taken a massive turn from working full time and exercising regular to been confined to my apartment as anyone else in the same position any feedback would be greatly appreciated also do they take into consideration that even the shortest walk aided results in been tired for the rest of the day

thanks for reading
