I've raised £3500 to buy a road worthy and damaged pavement worth mobility scooter.. in desperate need of help after 5 years

desperate need of help after five years ago, I broke both on my wrist coming out of my manual wheelchair the pavements where I live so badly damaged and on several angles going uphill and towards the road all at once . sitting in a manual chair is impossible. the NHS only allowed me to have one type wheelchair.. so my manual chair was taken and. I have a 4 mile an hour Wheelchair however after five years of fighting the council I can’t even use that in my own house .. so now I’m stuck in a manual chair,(saved 600 for one i could use secondhand) but its grating out my kneecap because of my unadapted property and unable to use the electricchair within my home,, ! my 4 mile an hour Wheelchair cannot cope either equally with the steep gradient and damage of the pavements. There are also a huge lack of drop pavements where I live, which means I have to go into the road. 4 yeafs ago I was actually physically assaulted just trying to go to my local shops and I have to also enjoy verbal abuse just to go to the shops and buy milk for me and my children.. And in fairness my 4 mph chair isnt road worthy.. I feel like because I have no choice says that I’ve lost the last five years of my children’s life,(33,19&( 14 on spectrum and adhd ) trying to fight for something I cant afford to buy ,, to have .. freedom…. I hold a full UK driving license. There’s no reason why I shouldn’t be able to go out and go to the park.the library to attend hospital appointments even.. because to try and get on the bus in my NHS electric, 4 mile an hour Chair is to problematics not only the none drop pavements, but the pavements around here are too badly damaged.. the hospital is only a mile up the road I could nip up there.. And get away from expensivetesco express to shop ,, this is the first time I’ve ever asked for help. I do not have friends not after five years of being almost housebound and I never grew up in this part of the country. .(was homeless 22 years as i was horsedraw until made illegal in 90s(lost all i had inc my children) . I was born into the system so no generational wealth to fall back on. I can’t even get a £50 overdraft… because I wasn’t in the system for 22 years... So after an exhausting 50 years,. I just like to try and make some memories with the few years i have left ,, i’ve lost use of the three limbs that I do have left. I have missed being in my youngest childrens lives as indoors were trapped in seperate parts of the house , my grandson is nine now I’m lucky if I see him three times a year…so ive not even been able to be an activerole in his life ,, so please help and give me choices .. freedom.. And one last chance to fight for my health..esp the mental impact thos has on me..
