My almost 17 yr old is struggling with anxiety most of which can be explained by his diffculty with change going into 6th form and some relationship issues (girls) which are fairly easy to deal with. I am however worried about a recent issue with a revamp of his bedroom. The addition of a new bookcase has completely thrown him. He hates that we've changed things - almost to the point of tears. He says he can't bring himself to move his books into the new bookcase, but doesn't know why. Is this behaviour odd or fairly typical of a teen who loves his dark, damp cluttered room?
