Dear person! I am not suggesting that you disclose, but from you post it is apparent that you have experienced some physical and/or emotional trauma in your life. Have hope, you can be free from this hypervigilance. EMDR is very effective, and there are other therapies that can help. Reach out to find a good practitioner. You are a wonderful child of the universe and you deserve to be free of the burden of anxiety and fear. Wishing you all the best!
