From my own experiences I sure wouldn't say laziness. My anxiety tends to do an all or nothing kind of feeling. I think if he has anxiety and depression bad I think it is great that he is finishing collage. That is a hard task when your mental health is struggling. I totally understand the fear and concern you have for your son. I would be doing the same thing. As a person who completely can be controlled by her anxiety, I know that "I can barely breath let alone have a life feeling." It really does take over your exsistance. Good luck to you and your son.
