Final answer:
The signs Enzo may need mental health treatment include his drinking of alcohol and withdrawal from social activities. Being overweight may also be relevant depending on underlying behaviors. Socializing with a small group and gaming are not necessarily signs of mental health issues.
Step-by-step explanation:
Enzo's behaviors that may signal the need for professional mental health treatment include drinking alcohol, withdrawing from activities, and potentially being overweight, if it stems from or leads to unhealthy eating patterns or psychological stress. Drinking alcohol, especially from a young age, can be a sign of attempting to self-medicate or cope with underlying issues. Withdrawing from activities that one previously enjoyed can be a symptom of depression or social anxiety. While being overweight in itself is not a direct indicator of mental health issues, it can be connected if it is related to unhealthy behaviors or emotional distress.
Having a small group of friends or playing video games are not inherently signs of mental health issues unless these behaviors coincide with signs of addiction, isolation, or are used as ways of escaping from reality to the detriment of daily functioning.
