My 14-year-old daughter was diagnosed with ADHD at age 7. Shortly before she turned 13, she began self-injuring herself in the form of cutting. Her doctor put her on medication for depression and anxiety. I'm wondering if all of this could be part of the ADHD? And if maybe the ADHD symptoms are manifesting differently now that the hormones of adolescence are affecting her. Or is this genuine depression and anxiety, something completely separate from the ADHD?
Her doctor hasn't been able to answer my questions very well and I'm feeling frustrated.

Has anyone else experienced anything like this themselves or with their child?
