I was in the same boat as a kid. My handwriting is so bad, for the essay portion of the state test we had to take one year, they got an exemption and let me use Notepad to type mine out because they didn't want to risk my grade if the person couldn't read my writing. This was in the mid-2000s.

These days I just disclaim to people when I hand them anything handwritten that I'm very aware my writing is terrible, and I will not be offended at all if they have to ask what it says.
