@Batters3aPark A you have other teens who are doing OK you know this is not your fault. (I have one teen who is absolutely loving lockdown, and regularly bounces around the house singing "I'm winning at lockdown!" before going off on his bike. This has nothing to do with my ace parenting! I have another who has become anxious, and another who is simply angry his nice life at uni has been interrupted)
I don't think it's the government's fault either, and while I do think it would be good if they could plough money into picking up the pieces, realistically that's not going to happen. It's going to cost families time and effort and a lot of money to manage their teens mental health.
Can you tempt your DS out with the prospect of a theme park or do you know someone who might need their dog walking? Often things suggested by people other than parents go down better with teens.
At times I just think, all you can do is model good behaviour: get up early, work hard, eat healthy, exercise and be nice.
