Depression during adolescence is normal and unless you went through a battery of tests I wouldn’t label this child ADHD. You need to figure out what is holding this child back. Is it a motivation issue, fear, or does this child simply think you will support them forever? It helps to teach a child how to budget. I would also get those driving lessons done. Driving is part of personal independence. Without driving, your child is at the mercy of others or public transportation.
