Obviously your son is not happy with his regular school program. His main interest appears to be reading (but maybe not the books they're reading in school), computers and art.

My first suggestion is, if you can afford it, to enroll him in after-school activities that cater to those interests, help him get around to different libraries (which are free) and encourage him to share his printed work and his artwork with his teachers and classmates. Maybe if his teachers see what he's doing it will give them some ideas about how to help him find his niche within the regular program.

I also suggest you try to find some time to do special things with him, like going to museums, science and computer exhibits. Throw in a visit to an ice cream store and make an afternoon of it. He needs to know that he's "okay", even though he's having a rough time in school.

Unfortunately, not all schools are into creating special programs for special kids, especially when the kid doesn't have a serious learning problem. Children like your son sometimes fall between the cracks. Ask for a meeting with his teachers (including computer and art teachers), the guidance counselor and the librarian. Maybe he can spend part of his school time working independently on projects that interest him and that use the skills or information that he needs in his regular schoolwork; maybe those teachers will be able to develop a good relationship with him so at least there can be some authority figures within in the school around whom he feels good.
