I am getting anxiety and panic attacks when I am worried or overthink. I had pounding and palpitation at that time. But, I am not feeling anything specific. I am going 20 minutes walk daily about 4 miles per hour and burning 200 calories. I lost around 11 lbs in the past three months. I have stopped taking chocolates, coke, red bull, etc., as well to help with weight loss. I have attached my CBC report here for your reference.
