As a dyspraxic, I feel you. Years of special classes to try and improve my handwriting and general coordination (this was before the condition was very well understood) and none of which really worked.
I have simply learned to avoid writing by hand as much as physically possible. It’s the main reason I was so interested in computers as a kid (again, before they were in everyone’s pocket) and I found programming as a creative outlet very liberating from the limitations of my physical abilities.
