I have hypervigilance as a side effect of ptsd. I've been trying for 3 years to find a cure for it. I went through cognitive behavior for a while with limited success. It's exhausting because I am always on alert and am sensitive to every sound and sight. My heart used to beat all day long and I had shallow breathing. It also gave me a lot of bowel issues as I had intense stress. I am thinking of going back to counseling again since I am depressed about it.
