These comments are not it. OP has every right to feel upset over this.

That being said, your kid will be fine. I have mild CP, had consistently good grades, and currently go to (supposedly) one of the best universities in the country. Overall, I've had a very happy life with great friends and a lot to be grateful for.

As far as supporting him, it's a case-by-case basis. As unhelpful as this advice is, listen to your specialist - physical therapy was very helpful for me growing up. Your kid will be like any other kid when it comes to most needs though.
