Struggling with Health and Finances After TBI and Divorce

I'm having a really hard time and want to see if anyone has any ideas. I'm 35 female, had major TBI in 2019 from an accident and haven't been the same since. On the side I run a horse rescue but physically am strugglingto do much. Also going thru a horrible divorce from a narcissistic man. I'm seeing a few different drs, some think i have POTS, some Fibromyalgia, some think I'm faking all together or have no idea bc ready results are mostly inconclusive. I've been trying to get SSDI/SSI bc I struggle to do basic daily tasks (getting dressed, dishes, walking, etc) but having no luck yet. Trying to figure out some way to make money so I don't get evicted. I'm already 2 months behind on rent and utilities. I'm open to a range of possibilities but I know I can't do an 8 hrs day or much physical stuff. A work from home would be best if it's flexible.
