My son is 9 and suffers from a fair bit of anxiety.
Hes a strange mixture as he is very confident and outgoing but can suffer from separation anxiety and is very emotionally sensitive.

He has for a few years had a very bad anxiety based swallowing problem (his throat closes up, feel tight and he cant swallow solids, he was on liquid diet for a long time) which is thankfully improving slightly. But new issues keep popping up.. For instance he sighs and breaths weirdly and says he cant breathe and get a full breath, even though the doctor has checked him out and hes fine physically. he does it at bedtime or when hes worried. Today he is worried the world will end due to the Large Hadron Collider in Switzerland! He also makes a fuss over me leaving his room when he goes to bed, and is convinced i will leave th ehouse ( i have never done so nor would I!)

Can anyone suggest ways to help him live a less anxious life? I suspect it could be heritary as i have always been a worrier myself
