Panic Girl- Fatigue is definately due to anxiety. When your mind is constantly worrying, you are using up energy and this is making you tired. I have found that the best way to beat fatigue is to stay active, like Anne said, as odd as that may sound. When you are engaging your mind with something, there will be nowhere for the anxiety to manifest itself. This will eliminate the fatigue. Not to be too personal, but I would change your username. Anything that reminds you of your anxiety will only lead to more anxiety. Sometimes it's the smallest things that can cause big problems. I would also stop looking up anxiety symptoms. Again, reminding yourself of your anxiety is the wrong approach in overcoming it. You need to focus on healthy things so that you don't give your anxiety a chance to manifest itself. I wish you well.
