help needed for disibility mobility at home/benefits/ etc

Hi
I really need some advice. My partner had surgery on his back this week due to pain for the last 3 yrs, but when he woke up from the op he realised that hes lost the feeling in his leg/foot:(.
Im trying to get everything in place for when he comes out of hospital and want to make things as easy as i can but im struggling and i have no idea what im looking for!

My questions are.....
Can i get help buying items to help my partners mobility issues at home?
Where can i get a wheelchair from as the hospital wont provide one?
Are there any support groups that i could join with him so he can talk about whats happened and how he feels?
I work nights, but ive been unable to go in as i have to be at home with our 2 young children (i dont have much support) and as im not going into work im not being paid. When my partner comes home i cant leave him as he cant have the children by himself and ill need to look after him. He works full time, but now he will have to hand in his notice. So we have no income coming in, can we get help ?

Im just so confused, cant believe this has happened. and honestly i really need any advice anyone could give xx
Thankyou for reading xx
