School Guidance counselors should be able to provide you with higher learning institutions (community colleges, four year colleges, etc) which have programs that specifically address the needs of students who have learning challenges.
I don't know if you have heard of vocational schools. The one that I have in mind right now is Job Corps. This program, depending on your location, teaches children 16-24 years old a specific job. They also help with life skills. You should look more into it. jobcorps.gov
I hope this helps.
