DS15 is doing brilliantly at school, is very popular with the other kids according to his teachers, but has recently fallen into what feels like depression. He describes it as feeling "glitched" and says he feels as if he's always waiting for something bad to happen, or worrying that something bad will happen to me for example. Over the past week or so he has been occasionally crying when talking to me, and is so clingy it's like having a baby again, he won't let me out of his sight. It's awful to see him in tears and I am trying my best to give him all of my time and to try and reassure him this is just something you can feel when teenage hormones are racing around your body. I felt exactly the same at 15 and would burst into tears at the drop of a hat with my own mum, for no reason at all. Am I doing the right thing trying to convince him this is a phase everyone goes through and it will pass? Does everyone actually go through this? He just keeps repeating that he's worried he will feel like this forever and I'm running out of things to say.
