So many things can be behind the anxiety. As a parent bejng supportive and asking your child what you can do to help support them and if they can tell you what causes the anxiety is huge. The reality is though parents are often the #1 biggest cause of child athlete's anxiety, yet so many are in denial about it. They think they are just doing what the kid wants and don't believe they push or whatever but they don't realize some of the tiny things they do cause it. It can be the look they get jn their face after a bad play, it can be the car ride home and the talk or energy happening there, it can be comments about their coaches or other players, it can be signing them up for something without asking, it can be trying to "encourage" them to "do more", the list is endless because the reality is parents, even great well meaning parents, are the cause of the overwhelming majority of the anxiety in their kids, it just is what it is. Learning how to manage it and lessen it are key components. There are outside factors too like school grades, peers, coaches. Or even internal pressure because of what they want for themselves. So finding the root cause and being supportive on their terms is huge.
