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.
