One thing about anxiety Lori is that it if it isn't dealt with it has a way of continuing to float around looking for new targets. It seems like at first you were worried that your son had dyspraxia, but it turns out he doesn't. You worried his hypotonia would prevent him from being able to do anything but he does musical theater. You worried he couldn't handle the scoliosis brace but he has. Then you were sure he had such significant handwriting problems that he course would be a disaster and no one would understand or help him. And, then he got an A+. Maybe instead of finding new landing spots for worry it would make sense to instead take time to reassess.
Even though he's never taken a class since kindergarten he got an A+.
He kept up so well nobody noticed if he had problems.
He was able to complete timed work.
His endurance got better.
He did things you didn't believe he could.
Nobody was mean to him.
It turns out if his muscles are smaller that really isn't significant enough to get the job done.
He showed he's capable of working hard.
Your son is 12 years old. If he wants to learn to read cursive he will. For many kids who didn't grow up writing cursive it is a learned skill. Our son noted at some point that he wasn't able to do it and I suggested he would with practice. And, he did. If he hadn't, no biggie.
If this is seriously posing a level of stress in a person caring for a disabled individual I'm going to suggest that isn't really about the cursive.
