My life is literally a dumpster fire that can't be extinguis

My life is literally a dumpster fire that can't be extinguished. My son will be 2-years-old in March and he was diagnosed with spastic/diplegic cerebral palsy in December. Fortunately his doctor is confident he'll be able to walk some day. Unfortunately that means weekly physical and occupational therapy sessions for the next 8-12 weeks with a treatment plan renewal every 8 weeks. That wouldn't be a problem is his father could get his license and we could afford a vehicle. He is also awaiting an official autism evaluation/diagnosis at the end of February. Allergy testing right after his birthday in March. Physical medicine and rehab consult in April to talk the possibility of needing braces for his legs. All three trips are out of town. He has to see his pediatrician in April for his 2-year "well child check". Due to all of his appointments, I don't have the time to maintain a job outside of the home. I paid a friend to take my fiance to the BMV to take his knowledge test and conveniently the system had crashed just before he got there and then my grandmother called in a hysterical panic saying my grandfather wasn't breathing right and he wouldn't wake up. So I had my fiance come home and my friend take me to my grandparents house so I could check on him. He was just severely dehydrated because he slept 24.5 hours straight. His cancer came back and has spread to his bones. He was mobile and seemed perfectly fine on January 3rd but by 10am January 4th he was bed ridden and completely out of his mind. He doesn't remember my son at all and he thinks I am my mother and that I'm 12 year old. I'm 23 and my mother passed in 2018. He has been having vivid dreams about going on hunting trips with his father (passed in 2016) and his brother (passed in 2017). My grandmother is not able to take care of him and I don't have the means to drop my life to help. If she were to give up and send him to a nursing home, they'd bill all three of his insurance companies, take his social security check (cutting her off because she draws off of him) and once he passes away, take the house. Then she'd be sent to an assisted living facility that I can't afford. Sure, I could try to get a handicap apartment and let her move in and add her to the lease but then our rent would be increased and we can't afford that either. It's a lose lose situation all the ways around. I'd give anything for a win for once in my life. I spent August 2021-November 2022 applying for jobs before I got his diagnosis and realizing I'd never have a real job again. We aren't really even surviving with my fiance's disability check. If you know of any work from home jobs that don't require a high school diploma/GED, a vehicle, or a start up fee, please let me know, I'm desperate.
