You sound likely to have dysgraphia, based on the fact I have all the same aspects and a dysgraphia diagnosis.

I am similar. If I physically write a couple times a week, my hand adapts though. It's a skill like any other.

Fountain pens are nice too since you don't need any pressure.

My writing looks a lot better if I just force myself to slow down and be deliberate, but honestly it's a constant battle. I'd definitely benefit from practicing penmanship on it's own.

Worth mentioning - for a long time, I found my handwriting messy AND my hand would tire out. When I was about a teen-ager, I decided to write in call-caps, very clearly. I've been doing that for a long time now, and worth giving a try.

teen-ager? call-caps? Cursive (several hundred years old) fixes this.. all-capitals(caps) or block-caps makes writing more laborious, possibly easier to read (which is why it used to be requested on hand-written forms?)

Several thousand more like.

Me too. And I can type so much faster and without thinking about it than I can write.

I've had many writing classes in school and different holders for the pen etc but I never managed to improve at all. Writing is just not for everyone.

Use a fountain pen. You can't press too hard: it bends and breaks the nib.

Disposable ones are good enough now, e.g. the Pilot V-Pen.
