You don't need anyone to tell you that teenagers are a difficult breed. They are on the precipice of adulthood, while being stuck in a body still trying to figure itself out through puberty. Male teenagers can especially be challenging because they are immersed in a culture where they are being told to always "man up," and "stop crying." As a result, they may deal with problems by either running away through avoidance and distraction (this can be manifested through being glued to their phones, constantly playing video games and exhibiting a lack of emotion) or by showing oppositional behavior. What teenage boys aren't taught in this culture, is how to cope with the daily stressors of life.
I've seen so many adults in their mid 30s and 40s who wished they could have gone back in time to learn how to process and cope with negative experiences and emotions.
The stigma of counseling is starting to change and it's better now than later to invest in counseling for your teenager. It'll save years of problems and equip them with the right tools and awareness that it is best to deal with negative stressors head on, coupled with healthy coping skills.
