Hi, I know this is almost two years later but I too feel the shakes and weakness in my body; like its coming from deep inside me shaking. I get cold and start to panic like my body is in a panic. When my body feel like it is panicking I notice that I am thinking about it more and more; and the more I think about it I panic more. It all started 6 years ago when I began stressing over a personal situation that still somewhat persists today. I would get this cloudy feeling in my head like I am not getting enough oxygen and it feel like something is moving in there. I dealt with it for a year and found out that I have sleep apnea. After being on a CPAP machine for about two months the cloudiness went away. Then I developed anxiety (a scared feeling like something bad is about to happen but nothing never does). I mostly felt this anxiety when I was sleeping; it would wake me up and would be so scared and body shaking and chills. I then changed my environment (I moved) to a much better environment that made me happy. The symptom seemed to have gone away but my stress followed me. Visited my doctor and found out that I have high blood pressure and borderline diabetic, in addition, over weight. I got myself in the gym twice a day. The gym help me lose the weight, lowered my blood pressure, and my diabetes where unfounded. Also, the gym helps me control my stress. I was all good, my cloudy head gone, scary feeling gone. This lasted for about two years; I gain my weight back, stop going to the gym and the cloudy head, anxiety, and scary feelings came back. In addition, the palpations of the heart started, feeling like I am going to die or something bad is going to happen. I absolutely hate this. But one thing good happen, I got control of what was stressing me and know I am on a mission again to lose the weight back in the gym, and take control of the diabetes.
Mostly, itâs all in the mind. Many trips to the emergency room and every time, normal. Just visited my Doctor and he did explain many things to me psychologically that is happing to me. And one thing that enhanced my panic attack and cloudiness in my head; I was suffering with a sinus infection. He gave me some antibiotics and it seems as though my cloudiness in the head is clearing up. Also, the stress, anxiety, and thinking about whatâs happening to you will make your symptoms worse.
Hope this help you out, it has made me do much better. In addition, your worries about death, please do not worry about death, it takes away from your happiness and you living your life.
