At times our worries stem from stressors in our lives and can be reduced by changing such things as our schedules. Other times worrying is more of an automatic way of thinking where one might dwell on irrational fears or be overly self-critical. Some people even seem to inherit a biological tendency to worry. I find myself wanting to ask more questions such as what you worry about, whether worrying is interfering with your sleep, whether it makes you uncomfortable in social situations or makes it hard to concentrate in class, and whether you ever have panic attacks. In any case, it is a situation you can do something about and you do not have to work through it on your own.
Anxiety is common and there are many good interventions for reducing and controlling it.
