did anyone else have trouble holding a pen/pencil as a kid?

i have diagnosed hypermobility syndrome (was supposed to get genetic testing for ehlers danlos but kept putting it off) and i remember back in the 2nd grade, the school had to buy me a specialized grip thing to put on pencils & “training” on how to properly write because for some reason i would squeeze the life out of any writing utensil i held, like to the point where it was unnecessarily painful. i have no clue why i did this or why i had such an issue with it, but now im wondering if this is actually common in connective/joint disorders? i don’t recall any of my classmates having this issue and i remember being really embarrassed about it 😭 in hindsight it sounds like kid me was trying to stabilize the joints in my hand
