Disabled mom

can someone genuinely help me i feel like ive run out of every option for my mom and i feel like im going crazy because there HAS to be some sort of solution.

I am 17 now and my mom was PERFECTLY FINE 4 years ago and then with no history she got breast cancer. thats not even the bad part. she developed paraneoplastic syndrome and when i tell you the last 4 years of my life have been the worst ever for both me and her im not kidding. she has recovered from cancer but now she can’t walk properly (she can walk with a walker inside but still somewhat shaky/slow and a wheelchair outside). I WOULD BE atleast somewhat “happy” if she could use an electric wheelchair but she also has hand mobility issues like they shake and move slow so she can’t use it that well. she still uses it to go downstairs but SHE CANNOT DRIVE. I am going to college next year and I cannot watch this happen to my mom because she will just stay inside the house all day with no freedom. like what are we even supposed to do. is there any solution???? even the buses here are horrible and she used to go to the hospital with them but WHAT happens when she gets off the bus? she can barely use the electric wheelchair and with the walker she would fall outside. my mom used to be so happy and i used to be so happy but now even when i am here she is not able to do what she wants to do. she used to have an amazing job but now cant even do that. her voice is affected by this stupid disease she isn’t able to talk properly without a slur. she doesn’t feel like she has a purpose anymore. now after i leave it will be worse. i need to find a solution please i seriously cannot do this
