I am really struggling as to how to help my 12yo DS. He has always been a "glass half empty" person, but it seems to be getting worse.
Often, last thing at night, he will talk about not wanting to going to school the next day. When I get him to break down what is good and bad about the day ahead, there always seem to be more good things than bad. He does well academically, and engages in plenty of other activities, but isn't naturally sociable and doesn't seem to make close friendships. There has been some low level teasing in the past - the school stepped in and dealt with it very effectively, but it is seems to be restarting from another quarter - DS seems ATM to be mostly cross with himself because he says he knows how to deal with it (bluff not caring until they give up) and just needs to do it.
I see much too much of myself in him. It's not just school related - if 10 nice things happen in a day at home he will still manage to focus on the one negative thing. I want to find a way to help him get his head up and look on the bright side. I don't mean to minimise how he is feeling, but there are a lot of positive things about his life, and I wish I could find a way to make him focus more on them and less on the less-good stuff 
All suggestions welcome...
