Hi manti1 and welcome.
I also have an 11 yr old son in a gifted program with dysgraphia and anxiety, and now an ADD diagnosis. I kind of expected the teachers at a school for gifted kids to understand at least the anxiety piece, but some don't. I have learned that I need to explain things very carefully, sometimes simply, including the emotional effects of LD's so that they don't label him (at least in their minds) as lazy. At one point the principal told me that he didn't know what 5 X 1 was. I had to point out to her that his frozen silence in the face of a question was anxiety, not lack of education.
The good news is that there are accommodations out there and some people who "get it" at the school. As he performs better in school using the keyboard, his anxiety level decreases!
Hang in there! Life is a little more complicated for my 2e kid, but he is growing up with so much more self-awareness than I ever had. And empathy for others. I think this will serve him well in the long run.
