<human>: due to nervousness my hand always get sweat & vibrate ? & due to this i always depressed & fear, i always try to avoid everything in my life ?
<bot>: Nervousness, sweating and vibrating are due heightened sympathetic nervous system activity. Anxiety can cause these symptoms.  Try these lifestyle modification: Eliminating caffeine, start an exercise program, improve your diet, and get support from family and friends.  Try some relaxation techniques like Yoga, meditation, and deep breathing exercises.  Dealing with worries is also one technique; like learning to postpone worries, and learning to accept uncertainty in your life. If nothing works there are some medications which reduce sympathetic activity, like propranolol. Best wishes,
