Anxiety is a generalized response to an unknown threat or internal conflict, whereas fear is focused on known external danger. Anxiety is a mental health condition that can cause feelings of worry, fear, or tension. People with anxiety are often prescribed medications. But it is essential to be careful with them. I personally checked the info about them on the Canadian pharmacy site and was frightened by the side effects. So, I started doing sports, yoga and meditation instead. All this works for me.
