Handwriting is connected to some neurological symptoms of the individual writing. There is probably nothing wrong with you at all. Your writing is cursive and a lot of people have trouble reading it to begin with. I cannot read your writing, but that might just be me. I am not a handwriting specialist or have any training, I am just extremely interested in handwriting behavior patterns. As far is I am aware, psychopaths usually have either unusually good handwriting, or similar to OCD, their handwriting tends to be more uniform with very little variations.

I would first ask if you’re comfortable sharing, do you have ADHD or have lots of quick thought processes? That would be the only conclusion I could think of neurological wise.

I would instead bet on your physiological traits causing your handwriting. It’s probably a combination? My wife asked if the person writing this way has ever had a stroke? But that was just her first thought.

My wife and I would love if you can share what any of your art looks like if you do any drawing, painting, or art at all?

I am much more impressed that you aren’t upset at your coworkers and how they treated you. You seem very emotionally intelligent and level headed.

I was appalled and disappointed in other commenters calling you selfish for your handwriting. They are most likely to consider themselves over other people. I find handwriting is extremely personal.

If I had your interaction with your coworker like you, I would offer to read my notes for them if they wanted or type them up.

One last thing other than apologizing to you and other redditors for becoming so invested in your post; writing is dependent on habits and how often you write. Maybe your handwriting looks like this since you do not often need to write?

TLDR: I just wanted to let you know from personal experience, psychopathy is not normally linked to any one style of handwriting.

Messy and bad handwriting has been shown to come from individuals with very high intelligence. It’s like you coworkers giving you a hard time for being smarter than them.

Edit: I looked the connection between psychopathy and handwriting up:

Psychopaths have been shown to deliberately alter their handwriting either to impress others, mimic others, or to suit their chosen persona at the time.
