My grandson who lives with me and has had years of health issues starting with cancer when he was 3 and the radiation has caused many back issues. He has had 43 surgeries and been put on pain medicine many times. He is on disability and has low self worth. His mother isn t part of his life and lives out of town. He has abused the pain medicine which causes lots of problems He has been to concelors but I think he may need other help. He really tells lies to the point we question everything he say. What can I do to help him
