Hi sorry to hear about your upcoming amputation, but let me say from the outset it’s definetly not the end of the world , firstly you seem to have what is needed a positive attitude and an acceptance which is one of the hardest things to overcome , I’ve had a prosthetic leg for 8 years
patience is something that is key in the beginning the saying don’t run before you can walk is definitely apt , but everything is achievable ,
in my experience the more you do the more help you will get , if you just want to sit in a chair you will get a “ basic” leg if you become more mobile you will get better legs ,
walking does take a bit of getting use to at first but it gets easier with time,
you Can apply for PIP my advice is use CAB to help you fill out the forms you should get it which then entitles you to a blue badge ,
With reguard to recovery just keeping fit will always help , and just keep that positive mental attitude ,
if you drive you will have to inform the DVLA as you may have to have adaptions done to your vehicle saying that you are due a left eg amputation so it just be automatic you can drive , I’m. Right be low knee amputee so I have to have a left foot accelerator adapter on mine ,
if you have any queries , questions or just want some moral support please feel free to PM. me at any time
good luck with the op
