I’m not sure how many parents we have on this board, but hopefully there will be someone you can connect with here. You might check out the link below for some info on support groups and resources for parents. The National MS Society would be able to tell you more about specific resources, and their contact info is at the bottom of the page.
Best of luck to you and your son. He is really lucky to have such a dedicated mom, and I’m glad you’re looking to get some support for yourself. J
