I am a 42 year old married male. I have two daughters and a son. I have a good job and works as a manager in the engineering sector. During the past two years, I noticed myself with down health. One night, I suffered dizziness in my head and felt cold in my limbs. I almost lose consciousness and after reviewing the doctor turned out that I have a rise in pressure and cholesterol. After follow-up, the consultant decided to spend a medicine to pressure and settled pressure after a period of time. As a result of this incident, I am with fear and anxiety. Now, I cannot focus and lasting grief. I have forgotten the names and sometimes I confuse myself. I am reluctant as I feel the rapid fatigue and lack of energy. I have nervous and acidity that does not rest with sleep. I always think that I have an undetected disease and visited most of the clinics in various disciplines. All my laboratory tests are normal except vitamin D, which is slightly low. Currently, I am on Enalapril, Natrilix and Atorvastatin.
Am I suffering from any disease? How can I find out whether it is organic or psychological? Most of the time I am upset, thinking about my situation and not enjoying my life. I am thinking as if I got Alzheimer's disease. Please help me.
