Sounds like you both are working hard and he's learning a lot. He's probably ahead of most kids his age. Don't be discouraged. I'm in a couple of teaching positions, one with my own children and one with our kids at church on Wednesday night. One thing I've learned is that when I start to get discouraged as a teacher, it permeates the whole class. And on the flip side, if I show excitement and desire to do the activity or lesson, they show it too.
I would take a good look at the curriculum and see where something needs to change possibly. I'd even talk to your son and see what subjects he absolutely dreads and see if something can be adjusted. You can't always cater to the child and they're going to have to do some things that require more work than they may want to put in, but you may find that there is an easy doable change that can be made.
I'm only in the kindergarten years with mine, so I'm sure I'll hit this point with mine later. But I had a similiar situation figuring out if my four year old, turning 5 a couple of weeks after the public school cut off date was ready for K or not. I was pushing and he was complaining. I had to do some serious praying and the Lord showed us some areas to change. We're doing K-4 and we've found a "happy place" with school:) Keep going and have fun with him.
One thought about handwriting...Is he writing in cursive or print? I didn't read all of the responses, to see if someone asked this. A lot of kids who struggle with print move on to Cursive and do great. A program I like is Cursive First. It goes along with Spell to Write and Read (SWR) that is the same approach as Phonics Road, but laid out differently. It's not as open and go, but we're using it because it fits us. For Cursive First, I like how they show that the cursive letters are just print letters "holding hands" Here's a link to an example on the SWR yahoo group that shows this.

Cursive helps with dyslexia because all the letters move from left to right and you don't pick up your pencil when you write them.
I hope it gets better and keep up the good work.
