Because.

So this is a pretty complicated subject, but here are the basics

Don’t judge yourself for having emotions. Remind yourself it’s ok to feel whatever you are feeling. It doesn’t make you broken or a bad person, and there is nothing to be guilty or ashamed of. Try to just accept the emotion without being sad or angry that you are experiencing it

Assess the situation. The first step is to identify what emotions you are feeling. (This may be help if you are stuck). The second is to figure out what thoughts or events (if any) triggered it. For example you might feel angry because you were treated poorly, or sad because you were thinking about all the ways you believe you have failed. Worksheets such as this one may help you with this and the following steps

Make a plan to address any issues now, or if the emotions are too intense, make a point to come back to this later. For example, if you are stressed about the amount of work you have due, your action could be to make a plan for what work to do each day, email your professor about an extension, and to identify and challenge the assumption that turning in a project late makes you a failure. DBT & CBT tools can help you identify and work through the process of doing this

Do something sensory. Focusing on your senses can be a very effective way to get out of your head, and allow your emotions to fade naturally. You could simply observe what’s around you (such as listing things you can see or hear), or you could create a pleasant experience by putting on a favorite song, using scents you enjoy, doing something with your hands, or some combination of these things.
