There are a lot of reasons why it would be perfectly justifiable to feel angry right now. Anger is usually an emotion that's tied with perceptions of injustice, and it's easy to see right now that there's are a lot of injustices going on in the world around us. So first and foremost, it's important to recognize that it'd be perfectly normal for you to be experiencing anger in times like these and might, in fact, be perfectly justifiable.
I would only say that it's a problem if you notice that your feelings of anger are happening so often or so intensely that they're either causing you distress or interfering with your ability to get things done in a productive way or maybe even impacting relationships that are important to you. In these cases, it may be useful to borrow some strategies from stress management and apply them to feelings of anger.
These include starting with just monitoring what are your triggers, what are the things that you seem to be reacting to with anger intensely, and then how do you know when you're angry. How does your body tell you physiologically that you're feeling anger? Does your heart race? Do you get flushed? Do you find yourself clenching your jaw or your fists more often? Do you find yourself tensing up all of your major muscles? Are you more agitated walking around pacing more, or are you feeling more irritated and potentially getting into conflicts or being snappy with people in your life more often?
These are all signs that you may be experiencing anger in a level of intensity that might not be so helpful. So if you can monitor for your triggers, then maybe you can get ahead of it next time and know, OK, these might be my high risk areas or situations, and then ahead of time, maybe practice some strategies that can be helpful in coping with your anger a little more effectively.
And these might include things like talking yourself down, coaching yourself, if you will, in ways that help you manage the situation better or practicing breathing or muscle relaxation in order to help calm your anger response that happens almost automatically in our bodies. May even be useful to give yourself permission to take a time out and walk away and just reset yourself before reengaging people in a more productive way.
Another way we like to think of it as giving yourself a chance to be assertive instead of aggressive. Assertiveness involves speaking up for yourself and maintaining your rights and expressing how you feel, while still respecting the rights of the people around you, that way you leave feeling good and also have the people around you leave feeling good as well. Taken together, you really do have a lot of ways in which you can help yourself cope when feeling angry.
