Is there any way you could do tax preparing from home via the internet? At first glance, it seems to me to be a skill where you might.
I had an accident and couldn't work full time for 3 years. There were a lot of things I just couldn't do. Talk to your therapists about what you can do, and for how long at a time. You can gradually increase the time that you can do things. Make sure you stretch yourself, but that you stop before it is too much for you - after an accident, the body needs to be really well listened to, so you don't take longer to get better. Do you run out of energy quickly, like I did? That's one place where I didn't listen to my body, and it took longer to get better.
I was really lucky that I had a stash and didn't have money worries to add to the depression I went through at the time. I hope you are as lucky. Sure, it meant FI took longer, but I was still alive. Part of the depression was how difficult everything became - work, hobbies, the things that made life worth living. Hopefully you have help with that.
Good luck with your recuperation and I hope that there are some positives for you. Looking back, because there were many things I couldn't do, I took up other things that I could, and my life is completely different than it would have been without the accident - I think for the better.
