Student, 24. Was a past smoker for 4 years with 5-6 cigarettes avg. Per day. Also was a drinker, twice or thrice a week. Left smoking since Feb 2016 and reduced my drinking to once a month since then. My weight is 83 (height 6 ft), reduced it greatly from 97 since my doc advised me to do so because of a slight high total cholesterol of 212 and a little high TSH, which are both now normal to 177 total chol. And TSH normal. But I feel that it has made me a lot anxious. Before exams I feel a lot anxious with palpitation, heart thumping, cold sweat etc. Also normally if I drink a beer or two, the next morning I wake up with a great anxiety and a feeling of heartattack. I am always scared of having a heart attack. Had an ECG recently, it ws totally normal, although my BP becomes high at 130/90 when I am anxious, comes to normal 112/70. Also sometimes it pains near my armpits when I am anxious. I am too scared, always have a feeling that I am gonna have a heart attack or so. Help me, it is hell.
