And how are things with you JKF? You posted a while ago about your job ending and thinking about becoming self-employed. I hope you've managed to make some positive steps with that and aren't worrying so much about your future employment, etc. Also you had some concerns about the father of your son being released and possibly trying to contact you. I hope that's been resolved.
Your friend says that she saw your son recently, looking fine and with a group of friends. They often seem to have two different personas - one full of drama for our benefit, and another that's 'fine'. I would try to hold on to your friend's description and try to not focus on the facebook posts.
Just my experience-laden viewpoint.
