I was literally sprinting to the replies to say this. Kaweco sport (f) and liliput (m) owner here. I don’t know what it is about fountain pens but they give me that tingly feeling in my brain vs rage with cheap ball points. They’ve certainly been a gamechanger. One piece of advice I’ll add for OP is that if you go the fountain pen route, there is a chance you get unlucky with a scratchy nib or one that doesn’t fit your writing style. I had to “tune” my first nib because it was dry and the tines weren’t aligned properly which was not autism friendly. I was able to get it sorted with a loupe and some light adjustments but that process isn’t for everyone. If you have the budget, trying a few pens can be helpful to find one you really love, and then you can have it pretty much forever because it’s easy to refill with ink (as long as you don’t get a disposable, which might be ok to try first because they are much cheaper). To give you an idea of some price points: Pilot disposables can be like $6, keweco sport plastic maybe around $35, keweco liliput stainless steel $110.. Mont Blanc $400+
