I'm new to the boards and finding them very helpful. My DS, nine, was also recently diagnosed with depression and anxiety, which appears to have been triggered by bullying. It took us months to realize how bad the depression was because he acted angry and irritable, not sad. He was beating up his sisters and blew up any time we asked him to do something he didn't want to do. He was also self-harming by pinching, scratching, choking, etc. himself. It has been extremely difficult for our family but things are slowly getting better. Hang in there.
