I had a child psychologist telling me that I strongly needed to consider medication for my 5 year-old child's anxiety because he was "just wired differently, so the only way he wouldn't feel intense anxiety was through medication."  
I knew he was having problems with gravitational insecurity, and had heard that there is a huge overlap between sensory processing issues and anxiety.  I told her that given his known sensory issues and the overlap of sensory and anxiety issues that I wouldn't consider medication without first trying OT directed at sensory processing issues.  We didn't even get to that point.  Less than a month of gymnastics and swimming classes, which are GREAT for sensory kids, and the anxiety disappeared.  In short, addressing sensory issues dissipated an anxiety level that had a professional crying "medication!  There simply is no alternative!"  
I would encourage you to consider an OT evaluation to see if your child might actually have sensory issues that are creating anxiety.
