Everyone says things they don't mean sometimes....I mean some of the verbal attacking your son does might be things he doesn't actually mean. But yeah even teens without any diagnosable mental issues can be very difficult, stubborn and sometimes do seem to just want more attention...but that combined with having mental conditions can make things really hard I mean I was a teen not so long ago and so yeah I know at times I was very difficult and sometimes it was to hide that I was struggling and actually felt lonely and vulnerable. If he's not in therapy or anything I'd agree its a good idea to maybe try to get him to go to therapy...and perhaps it would do you some good to look into it to have some more support coping with this a therapist who deals with this kind of thing could probably help you handle it better.
