Moms Medical Help

As I had last updated all of you I said my mom was very sick and sadly she still is she has what is called delirium where it sorta makes you not think normally. I have a lof my own medical issues with going to ER at times like with all this stress and getting food gets really expensive from doordash and instacart so I was hoping I could put some of this money to a really cheap car and maybe do lyft or uber part time and still keep my disability. I hate that I have to ask for money but my mom did everything for her and I when it came to money and paying rent and food and bills and I got thrown right into the middle of it when we do not have any money right now and I have to pay the rent and pay for transportation to my medical appointments and I have to do a lot for my mom if she gets to come home at some point. I am not sure if my mom will ever be back to normal or back to the same way she was the doctor said this is something that can go away I am praying that is what happens. I am really sorry to be asking for money for my mom and I but I really just don't know what to do and I am scared right now.
