When our world changes suddenly, it’s common to experience changes in our thoughts, feelings and behaviors. Feelings of anxiety, fear or worry are typical in stressful situations. Everybody is anxious. The COVID-19 pandemic has stressed everyone out. Between a fear of contracting or spreading COVID-19 to financial issues to a lack of social connection, this is a hard time for everybody.

I think it’s just a little harder for teens. They’re no longer able to celebrate birthdays with their friends, etc. But it goes so much deeper than that for most adolescents. Their SAHMO (Sadness At Having Missed Out) is real. They missed prom and traditional graduation.

Their freshman-year experiences won’t be the ones they’ve always envisioned. College freshmen wonder whether they should stay in school if it’s a remote experience. Why pay so much money to sit at home looking at a computer screen? But if they delay entering school for a year, if they’re allowed to (big if), what will they do all year? Who will be home? They are few good choices left.

Therapists are dealing with a sharp uptick in calls and new patients, especially from teens, and with good reason. Here are some typical reactions:

n Feeling stressed or overwhelmed, frustrated or angry, worried or anxious.

n Feeling restless, agitated, on “high alert” or unable to calm down.

n Being teary, sad, fatigued or tired, losing interest in usually enjoyable activities, or finding it difficult to feel happy.

n Worrying about going to public spaces, contracting germs or getting sick.

n Constantly thinking about the situation, unable to move on or think about much else.

n Experiencing physical symptoms such as increased fatigue or other uncomfortable sensations.

Everyone reacts differently to stressful situations, so you shouldn’t expect any specific reaction. Still, take a few moments to talk with the teens in your life about how they are feeling and what may help them during this difficult time. Remind them that all of these thoughts and feelings are common right now, and discuss simple self-care strategy that will help manage symptoms of anxiety and depression.

Here are a dozen mental-health tips and coping suggestions from Mental Health First Aid ( www.mentalhealthfirstaid.org ):

n Maintain a daily routine with consistent sleep, activity and study patterns.

n Stay connected with others and try to find moments of humor.

n Talk to people you feel comfortable with about your feelings or worries, then give yourself permission to stop worrying.

n Eat breakfast every morning, plus snacks and meals at regular times throughout the day.

n Limit coffee or energy drinks, as these will increase feelings of anxiety and make it difficult to relax.

n Look for patterns or be aware of situations that make you feel particularly worried or anxious. When you’re in these situations, try relaxation or distraction techniques, or ask a family member or friend to help.

n Relieve times of high anxiety with physical activity. Engage in regular aerobic exercise.

n Limit the amount of time you spend watching/listening to news media or social media if you are finding information about the COVID-19 situation to be overwhelming or distressing.

n Do hobbies or activities that you enjoy, that calm you down, or that focus your mind and body. It could be arts and crafts, physical activity, listening to music, reading, journaling, watching TV or movies, or chatting with friends by phone, videoconference or text.

n Understand that the people around you are also finding this situation stressful, and they might also be having difficulty controlling their emotions. Try to resolve conflict.

n If you continue to feel overwhelmed, out of control or unable to calm down after a period of weeks, seek help from a mental health professional.

n Take time for yourself. Make sure you remember to be kind to yourself and each other. We’ll work through this together.
