My 14 year old son.

My son is just going through a ASD and ADHD diagnosis. Life is tough. We are having very few good days. He is angry and argumentative most of the time. A big problem with it being the school holidays is boredom. His interest is shopping and theme parks so I can't take him to these places everyday. He gets up asking me what we doing today. If we are not going to a theme park or shopping he lays on his bed all day getting more frustrated. He is not interested in reading or watching T.V. When he was younger he would run up and down the garden or go on the trampoline and as he got a bit older he went on his scooter.Now he is older he won't do any of these things. He is not interested in any of my ideas. Please help any advice would be great.
