What causes my anxiety? Why am I so anxious? As if anxiety itself weren’t bad enough, not knowing what causes anxiety can make matters even worse. It’s natural to want to know just what is making you feel the worry and fear of generalized anxiety disorder, the dread of people and social situations of social anxiety disorder, the unease of separation anxiety disorder, the frights of phobias, or the death-grip of panic disorder/panic attacks. Knowing what causes any type of anxiety can be an important part of the puzzle and can help you move forward.
