Anxiety creates chemical reactions in the brain that make it feel "normal." But anxiety can also be cured. So the question is, how can you convince yourself that your brain is wrong, and that you can be anxiety free?
Don't believe anyone that says caffeine creates anxiety. Significant caffeine can affect anxiety, and caffeine does make you more alert so that your mind has an easier time thinking about anxiety, but caffeine itself does very little. There is some evidence it may even be GOOD for anxiety.
Did you know panic attacks can make you gassy? Anxiety can cause too much "air swallowing" and once you've swallowed that air, it needs an exit. Burping and flatulance is common. The good news is that the smell is minimal.
Are you drinking enough water? Dehydration can make all of your anxiety worse, which makes you fear your anxiety more in the future. Drink water, often, and consider switching out all of your sodas and other beverages for a nice glass of water.
Social media is creating its own problems. If you have children, make sure they know about problems with terms like "Thinspo" - the belief that looking at bone-thin bodies inspires weight loss. It doesn't, but parents don't know about the damage it's causing.
If you have social anxiety, one of the first things to do is get comfortable with yourself when you talk. Ideally you practice with people, but if not, try having a loud and powerful conversation with yourself in the mirror. Learn to speak up. Practice. Even with something as complex as social comfort, practice can make perfect.
