Hi, I do understand your concern. With the limited information, I can say that you are suffering from one of the anxiety disorders and may be depression as well. Anxiety as such causes autonomic symptoms like palpitations, tremors, sweating, etc. Had I been in your place, I would have immediately consulted a local psychiatrist as sooner the treatment starts, better is the prognosis. If i would have been your treating psychiatrist, I would have preferred a selective serotonin reuptake inhibitors together with teaching you some relaxation exercise. Hope you get well soon
