I struggled with my handwriting for years before I was diagnosed. I took courses in it, did hundreds of worksheets. I was teased and reprimanded many times. The result: if I write very, very slowly, I have beautiful script. But if I have to think while writing, or if I have to do it at all quickly--notes, for example--I'm back where I started.
After I was diagnosed, I realized I have serious disgraphia, and it ain't likely gonna change. So I adapted. I type everything now. Much better!
