Hello srinivas9912 Welcome to Health Care Magic I can understand your feelings, and for you reassurance I just want to tell you that this is not Depression, a lot of people have anxiety while facing public or while presenting a seminar. This thing is occurring in out of proportion. It is also called Social Phobia or Phobic Disorder. Individuals with social phobia usually have problem in facing public, in presenting seminars, in asking question in class or in group discussion, in expressing themselves to any person of higher status, some times they face difficulty in talking to female colleagues also. They can t face new people. In any of situation shakiness, restlessness, palpitations, sweating, dryness of throat are seen. But treatment is available for this problem, both psychological and medicinal treatment are available. Combination of these is best for early recovery. - Psychological management includes, Relaxation exercises, breathing exercises, yoga, meditation, assertiveness training. Try to practice the presentation at home alone again and again, then gradually present in front of some close friend, increase the level by presenting in front of small group. Make small goals in small steps and gradually proceed. - Medicines like Benzodiazepines like clonazepam can be taken in low doses for episodic control of anxiety. Some medicines like Propranolol are very effective in social phobia, they are taken just 1 hour before any presentation and help to diminish the signs of anxiety. Before starting any medicine kindly consult a good Psychiatrist. Thanks Take Care
