Dear Dan,

It feels like I’ve been cooped up with my wife and children for a year, and I’ve started to lose my temper about things that never bothered me before, like when the kids make noise. I can’t run away from home, but I don’t want to feel angry all the time either. What can I do to lower my stress level?

—Harvey 

Your desire to run away makes sense. One of the best things we can do when strong emotions bubble up is distance ourselves physically from the source of those feelings—in this case, your family. If you live in a place where you can safely go outside, next time you get angry go for a walk or a run and don’t come back for 30 minutes. That should be enough time for your emotions to subside.

You mention getting along with your family as the main source of stress, but like most people these days, you’re probably also worrying about bigger issues like your safety and your financial future. These kinds of worries make us feel helpless, and the best way to combat that feeling is to find ways to take control of our lives. This could mean waking up at the same time every day, starting an exercise plan so you can see your progress over time, or learning a new skill like cooking. Covid-19 will be with us for a while, and we need to figure out how to live with it without non-stop stress.

Dear Dan,

Working from home for the last few months has been bad for my eating habits, since it’s so easy to snack throughout the day. I’ve gained weight, and I want to go on a diet, but I’m still working at home, so the temptations aren’t going away. What diet would work best in this situation?

—Julie 

Planning a healthy diet is even harder now than usual, since going to the supermarket is more difficult and some ingredients are harder to get. To make things easier, try intermittent fasting, where you can eat anything you want for eight hours a day but fast for the other 16. Research shows that diets are easiest to keep when they have clear and simple rules like this one.

Dear Dan,

Recently my girlfriend broke up with me, and I can’t stop thinking about her. We were together for many years, and I was deeply in love. Now I can’t control my feelings: Every day I go from anger to mourning to fantasizing about getting back together. What can I do to start moving on with my life?

—Ari 

When someone we love dies, we have ceremonies like funerals and wakes to help us mourn. These rituals mark the conclusion of our relationship with the person we’ve lost, allowing us to focus on our pain, express it and put it behind us. If we kept fantasizing that the loved one was coming back, we’d never be able to move forward.

There aren’t any established rituals for mourning the loss of a loved one in a break-up, but there should be, so try creating one for yourself—some formal way of acknowledging that the relationship is over and won’t be coming back. This won’t take away your pain, but it should help you start recovering from it sooner.
