There are several strategies that you can use to become more calm:

1. Deep breathing: Taking slow, deep breaths can help you to slow down your heart rate and reduce feelings of anxiety. Focus on breathing in through your nose and out through your mouth, making sure that your exhale is longer than your inhale.

2. Meditation: Meditation can help you to calm your mind and reduce stress. You can start by sitting in a quiet place and focusing on your breath or using a guided meditation app to help you get started.

3. Exercise: Regular exercise can help to reduce stress and anxiety, as well as promote overall well-being. Aim for at least 30 minutes of moderate exercise each day.

4. Get enough sleep: Getting enough sleep is essential for mental and physical health. Aim for 7-8 hours of sleep each night, and establish a regular sleep routine.

5. Practice mindfulness: Mindfulness involves being present and fully engaged in the current moment. You can practice mindfulness by focusing on your senses and the world around you, rather than worrying about the past or future.

6. Prioritize self-care: Take time for yourself each day to do things that you enjoy, such as reading, taking a bath, or spending time in nature.

7. Limit your exposure to stressors: Identify the things in your life that cause you stress, and try to limit your exposure to them as much as possible. This may involve setting boundaries with people or taking a break from social media or news.

Remember, it's important to be patient and gentle with yourself as you work on becoming more calm. It may take time and practice, but with consistency, you can develop habits that will help you to feel more centered and at ease.
