Hello! Welcome on HCM! I read carefully your question and would explain that your symptoms could be related to different possible causes: - thyroid dysfunction - anxiety - depression. As all your performed tests have resulted normal, many other serious medical conditions have been excluded. Coming to this point, I would recommend checking first your thyroid hormone levels. If they result normal, I would recommend consulting with a psychiatrist. In my opinion an antidepressant can help improve all your symptoms. I would also advise you to avoid caffeine intake and perform a lot of physical activity (aerobics, Yoga, recreational sports), which can act like an antidepressant in your brain. Hope to have been helpful to you! You can ask me directly at any time if you have any other questions! Best wishes, Dr. Aida
