My son is diagnosed with ADHD and traits of autism . He is on a construction apprenticeship. He has taken the written and oral parts of his final exams and got a distinction in the oral . The final part is a construction piece over.2 days . His practice lessons have not gone well. He is really down and has convinced himself he cannot pass it . He manager has said he can resit if he fails and I have told him it doesn’t matter but he is so stressed out . He is talking about leaving his job. He says he is depressed and I don’t know what to do or say to “lift” him . It’s very sad seeing him struggle as I know he can do it and in his day to day work he does well . Any suggestions how I could help?
