G.A.D

Hi im 18 years old. My exams are going on currently and suddenly these days i've started having sleepless nights due to my heart beating very fast. Sometimes i think its a heart attack or cancer(i used to drink and smoke). But then later wen i went to the doctor he told me everything was fine with me which surprised me. Some say that im worried by my exams but honestly im well prepared for it and there's no such fear.

Please suggest how to end this feeling. Is it due to smoking/drinking? Is my health at risk?

Hi,first of all I think it is stress related but drinking and smoking make it worse.

But im not at all worried bout my exams and ive left drinking and smoking. Any other suggestion?

Looks like anxiety to me .You have to see a psychologist .At this stage i think the therapy help
