Hi Doctor,  I facing weakness in lefthand for sometime in day from last week, all movements of my hand is fine, and I feel weakness in it and also I am feeling full body weakness.. Consulted doctor two days back he suggested it is may be  due to stress or due to gastric problem and to be frank had some stress after my mother's deaths (after being paralysed for 3 yrs)  and I am having problem related to gastric very frequently say from last 4 to 5 months, after taking gastric control tablet (pantab or sompraz D) I feel much better  And also I am getting panicked even for small health issue(after mother's death)  like gastric or cold or cough and thinking much about it and I am getting panicked and depressed.  Due to this depression or panic all the negatives thoughts are rolling in my mind (constantly having fear of death), fear of being alone or travelling alone...  Also lost around 2 kg of weight in 2 wk I want to know what is the reason which is causing this and how to overcome..
