Take a deep breath, and understand the science behind your anxiety.
When you are worried or anxious, your worries are sending your brain a "WARNING" message. Your brain sends that warning message to the rest of your body which can make you feel uneasy. Sometimes you feel sick, scared, or just yucky. The worry traveling through your body makes is really difficult to think. So, take a deep breath and relax. Take a deep breath for the count of 4, hold it for a count of 7, and exhale that breath to a count of 8. Do it a couple times until you feel better. This will help your brain get rid of that worry so you can think clearly and not become overwhelmed with your worry.
Put down that cup of worry!
One of the things the Blah Blah Worry girls always try to remember when they worry about something is to put down the cup. Imagine if you are holding a cup of water. It's not very heavy at first, but the longer you hold it the heavier and heavier it becomes. You can't just hold that cup of water with your hands, because those muscles get tired. Your arms have to help, and when those muscles get tired, the rest of your body has to help hold it up. Your worries are kind of like that cup of water. They may not be very hard to deal with at first, but the longer you worry about them, the heaver they become. The more you think about your worries, the more of yourself it takes to hold them up. One thing you can do is imagine your worries are a cup of water and set down that cup of worry! Better yet, imagine yourself throwing that worry, smashing that worry, anything you need to imagine to stop thinking about that worry!
What's the Best that can Happen, What's the Worst that can happen.
On a piece of paper, make 3 sections. In the first section, write the best case scenario for your specific worry, and anything good that could happen for your worry. In the next section, write down the worst thing that could happen and any of the bad things that could come from your worry. Try to prepare for anything you can in the "worst case" section, but focus on the "best case" section. Try to only think of the best case things and do anything you can to make the things in that section happen. In the 3rd section, write down what actually happened. Keep this piece of paper and look back on it when you have future worries. Usually, what actually happens isn't anything close to the "worst case" section. Soon, you will realize your worries aren't as bad as they seem.
Be around supportive and kind people.
I had a hard time adjusting to a new dance studio, but my friends have always been there for me. They would hold my hand walking into class and give me big smiles to let me know they were there for me. I also have an amazing dance teacher who memorized something that helped me. Anytime she saw that I was nervous she said "God did not give us a spirit of fear or timidity, but of Power, Love, and Self Discipline" (2 Timothy 1:7). Knowing that she cared enough about me to memorize something that made me feel confident really made me feel comfortable and loved. So surround yourself with people who will be there for you and help you along the way, and be sure to always be there to help them, too!
Ask Someone who has been through it
I hurt my foot last week so I needed an x-ray. I was scared so I asked my brother, Jackson, if an x-ray hurt. I asked Jackson because he got an x-ray before. He said, "no it just tickles a little" then I was not scared anymore. If you are scared to go through a situation, you should ask someone who went through that same problem, so you know what to expect. I hope this helps.
