We Need To Know How To Deal With Our 19

We need to know how to deal with our 19 yr old daughter that has adhd and learning disabilities. Current she is enrolled in a state sponsored Vo Tech school for disabled children. She is due to graduate in Jan 2017 with a diploma in food service, all that the state said she tested capable of completing. Our concern is she cannot comprehend the concept of getting a job and supporting herself.
Thank You
