How do I calm down when my anxiety comes in?

Do breathing exercise and maybe take a walk. Realize that anxiety is your subconcious way of trying to protect you, whether it is justified or not. Quite often, it overreacts. Acknowledge that and your anxiety will normally come down.

I agree with CareNow, I always focus on my breath and breathing in deep and exhaling it all out. Walks help too, because you can realize by looking at nature and the world around you that everything around us is so vast and our anxiety is truly small in the big picture. A video i saw on youtube of a woman I follow who deals with anxiety says she likes to go to a public setting (which I know seems terrifying while anxiety is setting in) but she said to just watch and listen to the people around you and again, your problems and anxieties will start to dissolve after you see how small we are as individuals in comparison to the big picture, it is also calming to see others going on with their lives. I haven't personally tried this yet, I tend to get more anxious in public settings. But if it can help others it's worth it to mention. Something else i have found helpful is yoga, do a bedtime yoga practice. "Yoga with Adrienne" on Youtube has yoga practices specifically for anxiety, they are simple and anyone can do it, but it really does help so much and helps me get much better sleep. Yoga is truly so comforting and relaxing. Hope this helps!! :)

Breathe slowly and deeply in and out and just try to be aware of your breath and your body. Just try and keep breathing until the feeling of panic settles

If you're suffering from anxiety this very moment, see how you're breathing. Often you'll either feel like you're not getting a deep breath or you'll be breathing too quickly. These create hyperventilation, and hyperventilation is one of the main causes of most physical anxiety symptoms.So start breathing better. There is a method of relaxation known as deep breathing that can be effective, but it can take a while to practice. For now (since we only have one evening), simply slow down your breathing to 15 seconds minimum, and do your best to fight any urge to take a deep breath or cough.This will help you regain the carbon dioxide you lost when you hyperventilated, and improve blood flow to your brain.

Take a deep breath, try to not think too much even if it's hard, and if it's possible, find a calm place where you can sit down a moment.

I suggest you find you’re comfortable spot and talking to someone on what’s been stressing you out or causing you to feel this way. It’s always best to tell someone how you’re feeling.

There are many different ways you can calm down when anxiety kicks in. The first and maybe easiest way is to focus on your breathing. Start by inhaling for four counts (1-2-3-4). Then hold your breath for for 4 counts (1-2-3-4). Next, breathe out for 8 counts (1-2-3-4-5-6-7-8). When you focus on your breathing, you slow your heart rate down and reduce the cortisol levels. Another thing that you can do that uses all your senses is to notice five things that you see, four things that you hear, three things that you feel, 2 things that you smell, and 1 thing that you taste.
