Hello. Very Good evening. I'm Dr.Yogesh Kr Sharma. As per your history given, the provisional diagnosis is Anxiety Neurosis or Depression. Excessive smoking and lack of sleep will make you unhealthy anyway. Before coming to any one of diagnosis, kindly go for preventive Health checkup including Thyroid Function test. After having reports, come to practo chat for your treatment and counseling part and to have a final diagnosis, which is according to the symptoms suggestive of one of the above mentioned diagnosis. Until then Take Tab. Alprax (0.5 mg) , before retiring to bed. After taking this tablet,  you will feel relaxed and have a good night sleep. Further evaluation and treatment depends upon the reports. Kindly stop smoking gradually and not abrubtly. If you cannot take full meal,  then you should take fruits,salad and dates which are Very nutritious. Please don't worry unnecessarily and stressed out your self for nothing. Everything is happening to somebody for the goodness & wellbeing. At certain phase of life, everybody has Anxiety Neurosis or Depression, but the point is how you deal with this. Later I will send you to clinical psychologist regarding your issues which can potentiate the treatment. Take care until then. Have this tablet regularly 30 minutes before bedtime and no need to go anywhere after taking tablet. This is not sleeping pills, which you are thinking. This tablet will Slow down the activities of the brain and keep you cool and calm. Regards.
