Hi, for the last 8 months I've been suffering from the following symptoms: brain fog, fatigue, blurry vision, depressed mood, and muscle tension/weakness. I don't feel that classic anxiety symptom of the knotty feeling in my stomach or the constant sense of worry. Really I'm just baffled by the fog and that perpetuates my stress. I can't concentrate or focus at all. My life is full of work and all, but I don't consider it particularly stressful.
