Hello Welcome to HCM

You have complaints of anxiety due to exams or performance anxiety. Symptoms like excessive thinking and poor sleep during exams are main presenting complaints. Try to do relaxation exercises like yoga, or breathing exercises during exams to keep yourself relaxed. If the anxiety cause significant impairment in performance then consult a Psychiatrist. Commonly used anxiety drugs like Clonazepam should not be used because the drug can cause excessive sedation. Medicine like Propranolol is used to decrease symptoms of performance anxiety.

Consult a psychiatrist for medicines and if problem persists.

Thanks

Dear
Welcome to HCM
We understand your concerns

I went through your details. I suggest you not to worry much. Anxiety is fear of something which may or may not be true or may or may not happen in the future. Anxiety is known to produce so many weird symptoms which has no physiological back up. They tend to be just obsessive.

In your case, you had exam related anxiety disorder and you are still carrying it. If you had studied well, you will clear the exams. Any doubts? If you have fear of drowning, you learn swimming. If you have fear of plane and you have to do it, then you do it and fly. Therefore, forget about future. Do your duty well and have a positive attitude about future. Belief in god should help you achieving this.
