Very sorry to hear that
I don't know you well enough to make suggestions outright, but perhaps one or more of these questions will provide some ideas:
What other interests or talents do you have? Is it possible you could make a living at one of those?
Does the work location matter, or should you work from home?
Have you looked into vocational rehab? If you can no longer do your job for medical reasons, you may be eligible for training or other support.
