My son is ADHD and seems to suffer from rejection and sensitivity issues. He is in therapy and takes Adderall. He’s in college ( second time around). He seems to be doing well making All A’s and B’s. However he continues to doubt and uses negative self talk. How can I help him. He’s 32 and single. I support him so he can to go to school full time. I , too, need tools to help him structure his thinking. Can someone provide a resource?
