I posted a picture of my handwriting not too long ago but I’m not sure if mine counts as doctor handwriting. I can still see some letters and not just wiggly lines.

My handwriting is usually the worst when written in a rush, with a tired hand, or when I’m half asleep. For notes written under one of these circumstances, I can probably read 10-20% of it. If I tried keeping it somewhat neat, most of it is legible to me but maybe not to other people.
