Loss of interest, decreased concentration and attention, feeling low and disturbed sleep or appetite are some of the signs of depression.  Tremors, feeling anxious or nervous, sense of panic, sweating, increased heartbeat, feeling of impending doom, stomach discomfort, dizziness etc are signs of anxiety. These can be debilitating. If the anxiety us overwhelming, consult a psychiatrist at the earliest. With the right medication and counseling, it is likely your symptoms will improve. Other than that, try yoga, deep breathing, meditation, moderate exercise, progressive muscular relaxation and guided meditation. You can consult me for further management if required.
