So sorry for you. I too am fidning it difficult to get around so I got a mobility scooter. Hope you can try one if you you havent got one already. I use mine to take me and my drone off to fly.
Either way, very best wishes for your future.
thanks for all the comments guys I hope I will get back on my feet eventually but there is no point in having the P4 sitting around not being used its bad for the batteries anyway
