Hello thanks for asking from HEALHT CARE MAGIC The symptoms like fear, nervousness, anxiety, negative thoughts while travelling alone could be due to some phobic or anxiety disorder. In agoraphobia individuals may develop fear of unfamiliar places, or fear of closed spaces etc. I would advise you to consult a psychiatrist for evaluation of such symptoms and to make proper diagnosis. Behaviour therapy along with relaxation exercises have excellent roles in such symptoms. Relaxation exercise will help to reduce anxiety in anxiety provoking situations. If you fails to get relief with psychological treatment then medicines like SSRIs can help you. Medicines like Sertraline, Escitalopram, Fluoxetine etc are used for anxiety disorders. Consult a psychiatrist for proper prescription. Thanks, hope this helps you.
