The frist time you have to do is understand anxiety, and what it does to you. You have to do something about it and not let it take over your life. Anxiety cant hurt you and it is just a body reaction to stress in our lives. Its just a imbalance of chemicals in our brain that trigger the overwhelming sensation. Dont add to your anxiety with negative thinking and tell your self you are going to get trew it. Take time out of your day for like 30mins to 40mins to think about all your worries and what you have to do to change them. After that let them go. It helps you alot. Muscle relaxation is a good thing to do and it is easy. Start by choosing a muscle and holding it tight for a few seconds. Then let it go relaxing it. Do this with all your muscles try starting with your feet muscles and working your way up to the top of your head. Deep breathing is good to do too. Just breathe in slowly and make your stomach rise a little and hold your breath for a couple seconds and let it out slowly.
It help your anxiety to confornt the things in the past that have made you anxious. Every time you do it get easier and easier. And use meds if it helps. I hope this has help people out.
